Apple iPhone 4S release: live

The launch of the iPhone 4S last week was overshadowed by two things. Foremost was the death of Apple's co-founder and charismatic leader, Steve Jobs.
Jobs' failing health had been the only cloud on Apple's horizon in recent years. His death was not

unexpected - yet its abruptness was still a shock, as Jobs only stepped down as Apple CEO in August.
The other shadow to fall on the iPhone 4S was the sense of disappointment felt by some. This was not at all surprising: the hype around Apple product launches is now so great, and the level of - mostly uttterly incorrect - speculations so furious, that anti-climax is inevitable.
Frankly, if Apple were to announce it had created a perpetual motion machine and also harnessed nuclear fusion to produce limitless energy - unboxing the Holy Grail as its 'one more thing' - the event would still be greeted by seismic rumblings of discontent.
No surprise then that the iPhone 4S launch was dubbed "disappointing" and a "damp squib". Cupertino's shares even dipped on the revelation that Apple had not, as expected by scores of tech watchers, brought forth the fabled iPhone 5 after all.
The tech press' collective 'meh' was almost audible, not least because the gadget hounds have spent the past year predicting the arrival of the iPhone 5. And now their iPhone 5 vigil begins anew: another year of waiting, hyping and writing another thousand iPhone 5 stories. Little wonder they are blue.
But don't be deceived by this spectre of anti-climax. There's nothing shabby about the iPhone 4S. On the contrary, it's a very respectable update to a very popular smartphone.
Early indications suggest mobile consumers aren't fazed by the lack of the iPhone 5. Apple has racked up record pre-orders for its latest iPhone iteration. On Monday it announced iPhone 4S pre-orders had exceeded one million in the first 24 hours since the device was made available. This compares to 600,000 day-one pre-orders for last year's model, the iPhone 4.
If the iPhone 4S is disappointing there are an awful lot of technology companies that can only dream of being so dismal.
But let's play devil's advocate and ask exactly what features gadget hounds were hoping the mythical iPhone 5 would usher in? Earlier this year, silicon.com's sister site CNET News.com made a fine list of the top 20 most-wanted iPhone 5 features.
Top of this wish list was 4G support - a next-generation network technology that hasn't even been rolled out in the UK, since the spectrum required to underpin it hasn't gone under the hammer yet. So does the whole world - that is, not just the US where 4G has been rolled out - need a 4G iPhone? No, not yet.
Another coveted feature according to the list was near-field communications (NFC) - a technology that enables contactless payments and content sharing between NFC-enabled devices. Again, the infrastructure required to render NFC useful to the masses, rather than an innovative gimmick for the techie few, is not yet in place. In the UK, for instance, around 40,000 retailers accept contactless payments - so that's an awful lot of shops that don't.
On the NFC content-sharing front, RIM has just announced it will incorporate a 'tap to share' system called BlackBerry Tag into the next update of its smartphone OS. There's no firm launch date on this - and RIM's handset portfolio currently includes just two NFC handsets - so finding another NFC-owning BlackBerry user to contactlessly share content with is going to take considerably longer than contactlessly sharing the content itself.
Technology features in and of themselves are meaningless. What matters is whether they contribute something positive to the user experience. Which is why saying no to emerging technologies such as NFC is the right decision for Apple at this time.
It's also why, when Apple upgraded the iPhone's camera to eight megapixels, rather than cramming more megapixels atop the same sensor, it included a larger sensor to ensure better quality pictures - not just a spec sheet bump. Unlike other companies that play spec sheet top trumps - often in a misguided attempt to leapfrog Apple - Apple prioritises the user experience. That's not a bug, it's a feature - arguably Apple's defining feature.

Apple's IPhone 4S Sales May Reach 4 Million This Weekend

Apple Inc. is poised to sell as many as 4 million units of its new iPhone 4S this weekend as customers around the world clamor for one of the last products developed under Steve Jobs.
The device, available today in the U.S., Australia, Canada, France, Germany, Japan and the U.K., is

projected to outperform last year's introduction of the iPhone 4, which topped 1.7 million units in its introductory weekend. For the iPhone 4S, most estimates range from 2 million to 3 million, with Yankee Group analyst Carl Howe predicting sales of as much as 4 million.
The release represents the end of Apple's era under Jobs, who died this month after an eight-year battle with cancer. The iPhone 4S has received mostly positive reviews for its voice- recognition software, speedier processor and improved camera. The device also provides Apple with fresh ammunition in its fight against Google Inc.'s Android software, which will appear on a host of new smartphones in the year-end holiday season.
“It's going to easily outpace any previous launch,” said Charlie Wolf, an analyst at Needham & Co. in New York. It helps that the iPhone is available on the three largest U.S. carriers for the first time, which will bring in new buyers, he said.
Apple also has released an update to its iOS mobile operating system, which customers can download to their existing devices. The software comes with 200 new features and a Web storage service for synchronizing photos, documents, music and other files across different Apple gadgets.
Google Competition
While the iPhone is the best-selling single smartphone, all of the devices running Google's Android operating system account for more of the industry's sales. HTC Corp., Samsung Electronics Co., Motorola Mobility Holdings Inc. and other manufacturers have adopted the software. Google offers Android for free and then makes money on mobile advertising and services. That revenue now accounts for $2.5 billion a year, the company said yesterday when it released quarterly results.
Apple's shares have jumped more than 10 percent this week, boosted by speculation that the iPhone 4S will be a hit. The stock closed at $408.43 in U.S. trading yesterday, making Apple the world's most valuable business. Its market capitalization now stands at $378.7 billion, compared with $371.3 billion for the second-ranking company, Exxon Mobil Corp.
In German trading, the stock today rose 1.4 percent to the equivalent of $412.42 as of 10:01 a.m. in Frankfurt.
‘Memory' of Steve
About 25 customers were lined up outside Apple's Midtown Manhattan store at lunch yesterday. In Australia, the first country where the product went on sale, Jackie Guo, 25, and his girlfriend, both students at Macquarie University, said they lined up as a tribute to Jobs.
“It's the iPhone for Steve, it's for the memory of Steve,” Guo said. “It was the last product he worked on. He pushed this company to become a viable company. His ideas are better than others. They make the market more hungry for the product.”
In Frankfurt, Grigory Stolyarov, a 27-year-old employee of Dekabank Deutsche Girozentrale, spent the night in front of the store in the city's main shopping street. He had put on two pairs of socks, sweaters and jackets to weather the first near- freezing night of the fall season and be among the first 20 people in the line of more than 1,000.
‘It's a prestige thing,” said Stolyarov, who picked up three iPhones and already owns an Apple iPad 2 tablet computer. “I feel like an onion and I definitely need some sleep,” he said.
Makeshift Memorials
In Tokyo, about 80 people were lined up a day before the debut and there were more than 800 people by 8 a.m. at the Ginza district store.
Jobs's admirers have turned storefronts into makeshift memorials, adding a solemn tone to the frenzy that accompanies the company's product releases. Jobs co-founded Apple and returned to the company after a 12-year absence, rescuing it from near-bankruptcy.
“They are going to sell out,” said Yankee Group's Howe, who is based in Boston.
High demand for the new iOS 5 software contributed to glitches at Apple even before the iPhone 4S went on sale. Customers downloading it to their older phones overwhelmed the company's servers, making it harder to upgrade.
Sell Out
Apple hasn't said how many people were affected. The wait time to get a call back from an Apple support representative via the company's Express Lane service is much longer than usual. Typically, an Apple rep will call back within a few hours. Now, the earliest appointments aren't for days.
Trudy Muller, a spokeswoman for Cupertino, California-based Apple, declined to comment
The iPhone 4S will go on sale later this month in 22 additional countries, including Ireland, Italy, Mexico and Spain. Apple didn't say when it will be available in China, a country Chief Executive Officer Tim Cook has said will be critical for the company's future growth.
Apple said earlier this week that it had received more than 1 million preorders for the iPhone 4S. The three U.S. carriers selling the device -- AT&T Inc., Verizon Wireless and Sprint Nextel Corp. -- sold out as well. The demand puts Apple on pace to sell a record number of iPhones in the quarter ending in December, according to the analysts' reports. Gene Munster, of Piper Jaffray Cos., estimates that Apple could sell more than 25 million iPhones this quarter.
Top Moneymaker
The iPhone, first introduced in 2007, has become Apple's top moneymaker, accounting for almost half its total revenue. Sales from the new model won't be part of the fourth-quarter financial results Apple is due to release on Oct. 18. Even so, profit rose about 60 percent in the period to $6.9 billion on sales of $29.5 billion, according to the average of analysts' estimates compiled by Bloomberg.
The release of the iPhone 4S, along with new Android models, should mean that smartphone users account for the majority of U.S. mobile-phone customers for the first time, said Roger Entner, an analyst at Recon Analytics LLC in Dedham, Massachusetts.
Apple controlled 19.1 percent of the smartphone market in the second quarter, according to research firm IDC, ahead of Samsung, Nokia Oyj and Research In Motion Ltd.
Few companies can build excitement around a new product the way Apple can, Yankee Group's Howe said.
“This is what they are good at,” he said. “They know how to make a big launch weekend.”

Here’s the full change log for iOS 5 beta 5

Apple just pushed iOS 5 beta 5 out to developers and wouldn’t you know, we’ve got the full change log for you to feast your eyes on. Hit the jump for all the iOS 5 changes you can handle.

Thanks, Jean!

NOTES AND KNOWN ISSUES

The following issues relate to using the 5.0 SDK to develop code.

Accounts

When creating an iCloud account, you can use any Apple ID as long as it is a full email address and not a MobileMe account. If you have a MobileMe account, you can move that account to iCloud. You can find more information on iCloud at: http://developer.apple.com/icloud

When setting up an iCloud or MobileMe account using the setup assistant and leaving Find My iPhone on, it might actually turn Find my iPhone off after the setup. Please verify in Settings/Mail, Contacts, Calendar/YourAccount that Find my iPhone is toggled On after leaving the setup assistant.

NEW: Enabling iCloud services in Setup Assistant may not always be saved correctly. After completing Setup Assistant you should visit Settings > iCloud to verify the state of the iCloud account. If you have multiple iCloud or MobileMe accounts configured on the device you should also visit each of those accounts in Settings > Mail, Contacts, Calendar to verify each account.

It is recommended that you disable Bookmarks on multiple accounts. If they are enabled, the results might be undefined.

AirPlay

Starting in iOS 5, video content in applications and websites are AirPlay-enabled by default.

iOS 5 supports AirPlay of video via AV Foundation.

Apple TV

Apple TV Software beta enables users to mirror the contents of an iPad 2 to an Apple TV (2nd generation) using AirPlay. This beta software also enables Photo Stream on Apple TV so users can access photos stored in iCloud. Apple TV Software beta is being provided to test the latest AirPlay functionality with your iOS 5 apps and web sites. If you wish to install Apple TV Software beta on your device, you must first register your device UDID in the iOS Developer Program Portal.

Calendar

Birthday calendars are not currently available via the icloud.com website or in Windows. They will be available in a future release.

NEW: The default calendar is still the On My iPhone calendar despite setting up an iCloud account during Setup Assistant. As a workaround, reset the default Calendar after finishing Setup Assistant in Settings > Mail, Contacts, Calendar > Default Calendar.

NEW: Pushing iCloud Calendar data is not working in iOS. To sync your iCloud Calendar, launch the Calendar app or refresh the calendars manually using the Calendars button in the top left corner.

Core Image

Several filters have been added since beta 1. The current list now includes the following filters:CIAdditionCompositing, CIAffineTransform, CICheckerboardGenerator, CIColorBlendMode, CIColorBurnBlendMode, CIColorControls, CIColorCube, CIColorDodgeBlendMode, CIColorInvert,CIColorMatrix, CIColorMonochrome, CIConstantColorGenerator, CICrop, CIDarkenBlendMode, CIDifferenceBlendMode, CIExclusionBlendMode, CIExposureAdjust, CIFalseColor, CIGammaAdjust,CIGaussianGradient, CIHardLightBlendMode, CIHighlightShadowAdjust, CIHueAdjust, CIHueBlendMode, CILightenBlendMode, CILinearGradient, CILuminosityBlendMode,CIMaximumCompositing, CIMinimumCompositing, CIMultiplyBlendMode, CIMultiplyCompositing, CIOverlayBlendMode, CIRadialGradient, CISaturationBlendMode, CIScreenBlendMode,CISepiaTone, CISoftLightBlendMode, CISourceAtopCompositing, CISourceInCompositing, CISourceOutCompositing, CISourceOverCompositing, CIStraightenFilter, CIStripesGenerator,CITemperatureAndTint, CIToneCurve, CIVibrance, CIVignette, and CIWhitePointAdjust

GameKit

Match data for turn based matches is currently limited to 4 KB of data.

NEW: When logging in to Game Center, the password may clear and login may not complete. Trying a second time will succeed.

NEW: In this beta, GameKit Invites may fail. As a workaround, try restarting the device.

iBooks

iBooks 1.2.2 may fail to display some text or images in books. Please update to iBooks 1.3 in the App Store.

iCloud Backup

As this is beta software, it is recommended that you do not use the iCloud services to store any critical data or information. If you enable iCloud Backup, automatic backup with iTunes when syncing will be disabled. We also suggest that you manually back up your device with iTunes. Backups made with earlier versions of iOS 5 beta will soon become incompatible, and will no longer be available. It is strongly advised you upgrade to this version of the iOS 5 beta in order to continue backing up your devices. If you encounter errors restoring from a backup, or enabling a backup more than one hour after signing into iCloud, try deleting your iCloud account from Settings and adding it back. If errors persist, please try erasing your device and initiating the restore again.

iCloud Storage

During the iOS 5 beta period, any documents stored on the servers might be purged periodically before GM. Therefore, it is highly recommended that you do not store any critical documents or information on the servers.

NEW: Provisioning Profiles no longer need to be enabled for iCloud in the iOS Provisioning Portal. All newly generated provisioning profiles are now automatically enabled for iCloud. If you are using an Xcode managed Team Provisioning Profile, click refresh in the Xcode Organizer to obtain a new iCloud-enabled profile. To enable all other provisioning profiles for iCloud, simply regenerate your profiles in the iOS Provisioning Portal.

If your application is using the NSMetadataQuery class, you must set a predicate, even though the predicate itself is ignored.

In this beta, the setSortDescriptors: method of NSMetadataQuery is not supported.

FIXED: To use iCloud prior to beta 5, you had to manually specify various container identifiers (your application’s Display set) within an Entitlements file for both of your Mac OS X and iOS projects.Starting in beta 5, to enable iCloud storage within your apps, simply click the “Enable Entitlements” checkbox in the Summary pane of your project. Xcode will create a custom entitlements file for your project that automatically includes your Team ID. You can add additional iCloud Container values as required by your application. (Note that you must regenerate your existing provisioning profiles, either with Xcode or in the iOS Provisioning Portal, to use iCloud storage.)If you specify a custom identifier string for your iCloud Key-Value Store or iCloud Container entitlement values, you no longer need to prepend your Team ID to the beginning of the string. Xcode will prepend your Team ID to these entries automatically

The container identifier string you pass to the URLForUbiquityContainerIdentifier: method of NSFileManager MUST include the team ID at the beginning of the string. As a convenience, if you pass nil, Foundation uses the first document container ID specified in your app’s entitlements.

There are issues using the Cloud Storage document API in conjunction with protected data which can lead to data corruption.

FIXED: In this beta, document-based applications cannot always detect when files change, move, or are deleted out from underneath them.

In this beta, file presenters (objects that adopt the NSFilePresenter protocol) do not receive some of the messages that they’re supposed to receive, especially:

presentedItemDidChange

presentedSubitemDidAppearAtURL:

presentedSubitemDidChangeAtURL:

You can workaround this by implementing the relinquishPresentedItemToWriter: method and checking to see if the writer actually wrote when your file presenter reacquires. You can also use FSEvents to observe file system changes

In this beta, messages about changes to files in a directory are not getting delivered to objects that adopt the NSFilePresenter protocol.

While reporting a bug related to the iCloud storage interfaces, please include the logs collected during your debugging session. To generate these logs, you must install a special debug profile on your device.The debug profile can be obtained from http://connect.apple.com. This profile enables the generation of debug logs that are needed to diagnose any problems using iCloud storage. The instructions to collect the logs are:

Install the profile. (The easiest way to do this is to mail it to yourself and open the attachment on their device.)

Reproduce the bug.

Sync with iTunes to pull the logs off your device.

Attach the logs to your bug report. You can find the logs in ~/Library/Logs/CrashReporter/MobileDevice/DeviceName/DiagnosticLogs.

These logs can grow large very quickly, so you should remove the profile after you have reproduced the problem and pulled the logs for the bug report.

NEW: File names are case-insensitive in OS X but case-sensitive in iOS. This can lead to problems when syncing files between the two. You should take steps on iOS to avoid creating files whose names differ only by case.

iMessage

iMessage beta 1 will be unable to communicate with iMessage users on beta 2 or later.

iPod

NEW: When using the volume buttons on the device, or on headphones, the volume slider in the UI of applications may not update even though the volume level has changed.

iTunes

The version of iTunes that comes with beta 5 cannot sync devices that have the beta 4 software installed. To avoid this problem, do the following:

Sync any devices that have beta 4 installed to the version of iTunes that came with beta 4.

Upgrade iTunes to the version that comes with beta 5.

Connect the device and install the beta 5 software. (Understand that you might see a failure to sync error when you first connect the device.)

After installing the beta 5 software, restore from your the backup you made in step 1.

Videos purchased from the iTunes Store do not play on a 2nd generation AppleTV over AirPlay with iTunes 10.5.

Location

FIXED: The startMonitoringSignificantLocationChanges method of CLLocationManager does not cause applications to be resumed or launched in the background for significant location change updates. However, if a backup from a previous software version (where an application was monitoring significant location changes) is restored to the device, significant location change monitoring will continue to cause that application to be resumed or launched in the background.

Mail

FIXED: Forwarding a message with attachments included does not attach the file and the message compose screen does not change from “Loading….”

NEW: When changing the host name of an email account in settings, blank messages may be seen in the unified inbox. As a workaround, delete and re-add the account instead of changing its host name.

Music Library

FIXED: Some songs are missing their album artwork after changing the device library via syncing.

OpenGL ES

FIXED: In iOS 5.0 beta 4, several OpenGL ES extensions have been moved from the APPLE namespace to the EXT namespace, causing some API to be renamed. The altered extensions are EXT_color_buffer_half_float,EXT_occlusion_query_boolean, EXT_separate_shader_objects, EXT_shadow_samplers, EXT_texture_rg, EXT_debug_label, and EXT_debug_marker.

OTA Software Update

If you are doing an OTA software update, you will need to re-sync your photos with iTunes.”

Personal HotSpot

FIXED: In this beta, iPhone 4 device cannot join personal hotspot even if it is on due to a non functional Wi-Fi tethering on these devices.

Photos

FIXED: If you apply red-eye adjustments in iOS, and import your image into the iPhoto seed build, the red-eye adjustments will not appear on that image in iPhoto. As a result, subsequent syncing of your image back to the iOS device from iPhoto will not show the red-eye adjustments.

NEW: When restoring photo libraries from an iTunes backup, some photos may not appear in the Photos application after restore. Please back up your photos before updating to iOS Beta 5.

Simulator

Location services are not functional in iOS 4.3 simulator running on Mac OS 10.7 with Xcode 4.2.

Springboard

Push and local notifications for apps appear in the new Notification Center in iOS 5. Notification Center displays notifications that are considered “unread.” In order to accommodate push and local notifications that have no “unread” status, developers can use their application badge count to trigger a clearing of notifications from Notification Center. When an application clears its badge count (by setting it to zero), iOS 5 will clear its notifications from Notification Center.

FIXED: iOS 5.0 terminates VoIP applications that are resumed in the background for incoming network traffic with extreme frequency. Developers are encouraged to make sure all incoming data is read from VoIP sockets to avoid this condition.

NEW: The UIPrerenderedIcon key (in the Info.plist file) is not honored in this build.

StoreKit

NEW: In-App purchase will not work for developers testing their apps with the iTunes Sandbox.

Twitter

FIXED: When tweeting your location from Safari and exiting before the location can be established, the location arrow will stay in the status bar. The arrow can be removed by killing Safari from the task switcher.

UI Automation

FIXED: Instruments overwrites the loaded automation script, even if another program is editing it.

FIXED: The play and record buttons in the Automation instrument script editor may not work properly after targeting an application that was launched by a trace session and has ended. They may also not work if you target an application that was suspended. If you run into this problem and it persists, you may need to close and reopen the trace document to get back into a functional state.

FIXED: When capturing actions into a script using the Automation instrument, interfaces with web views or table cells that contain a high number of off screen elements may take an extremely long time before returning with an expression.

The lock() and unlock() functions of UIATarget have been replaced with the lockForDuration(<seconds>) function.

Starting in iOS 5 beta 2, you can now trigger the execution of an UI Automation script on an iOS device from the host terminal by using the instruments tool. The command is:

instruments -w <device id> -t <template> <application>

When using the cli instruments for UI Automation you can now target the default Automation Template and pass the script and results path into the tool as environment variable options. For example:

instruments -w <device id> -t /Developer/Platforms/iPhoneOS.platform/Developer/Library/Instruments/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate <application> -e UIASCRIPT <script> -e UIARESULTSPATH <results path>

UIKit

Starting in iOS 5 beta 3, the exclusiveTouch property of UIControl has returned to its original default value of NO.

Returning nil from the tableView:viewForHeaderInSection: method (or its footer equivalent) is no longer sufficient to hide a header. You must override tableView:heightForHeaderInSection: and return0.0 to hide a header.

In the iOS 5 beta, the UITableView class has two methods to move one cell from one row to another with defined parameters. These APIs are:

moveSection:toSection:

moveRowAtIndexPath:toIndexPath:

Using the UIWebView class in Interface Builder, setting transparent background color is possible in iOS 5. Developers compiling against the new SDK can check their XIB for the UIWebView transparent setting.

In the iOS 5 beta, the UINavigationBar, UIToolbar, and UITabBar implementations have changed so that the drawRect: method is not called on instances of these classes unless it is implemented in a subclass. Apps that have re-implemented drawRect: in a category on any of these classes will find that the drawRect: method isn’t called. UIKit does link-checking to keep the method from being called in apps linked before iOS 5 but does not support this design on iOS 5 or later. Apps can either:

Use the customization API for bars that in iOS 5 and later, which is the preferred way.

Subclass UINavigationBar (or the other bar classes) and override drawRect: in the subclass.

The indexPathForRow:inSection:, section, and row methods of NSIndexPath now use NSInteger instead of NSUInteger, so that these types match with methods defined on UITableView.

Touch events are not getting forwarded to the view in the cameraOverlayView property of UIImagePickerController.

We have changed the behavior of scrollToRowAtIndexPath:atScrollPosition:animated: such that UITableViewScrollPositionTop and UITableViewScrollPositionBottom now adjust for the top and bottom portions of the contentInset property.

WebKit

In iOS 5, a new inherited CSS property, -webkit-overflow-scrolling, is available. The value touch allows the web developer to opt in to native-style scrolling in an overflow:scroll element. The default value for this property is auto, which allows single-finger scrolling without momentum.

NEW: In beta 5, accessing sites that use client side SSL certificates does not work and may cause the application to crash.

The WebKit framework has picked up a newer WebKit engine, which closely matches Safari 5.1. Some areas to be aware of with the new WebKit framework on iOS:

There is a new HTML5-compliant parser.

Text layout width may change slightly because word-rounding behavior now has floating-point-based precision.

There is improved validation of the <input> form field, which includes removing leading zeros and number formatting.

Touch events are now supported on input fields.

window.onerror is now supported.

There is a new user agent that does not have locale information in the User Agent string.

NEW: URLs are now canonicalized by making the scheme all lowercase. If a fake URL is used to pass information from a UIWebView back to native code, make sure that the scheme is always lowercase, or that the native code compares the scheme in a case-insensitive manner.

Wi-Fi Syncing

In iOS 5 beta 4 and later, wireless syncing is now available on Windows as well as the Mac. (This support requires OS X 10.6.8 or Lion.) You will see an option to enable wireless syncing when you connect your device to iTunes with the USB cable. It is recommended you perform your initial sync with a cable after restoring your device.

Wireless syncing is triggered automatically when the device is connected to power and on the same network as the paired computer. Or, you can manually trigger a sync from iTunes or from Settings > General > iTunes Sync (same network as paired computer required).

If you find issues with apps, media and/or photos synced to your device, you can reset then resync. From Settings > General > Reset, choose Erase all Content and Settings. Then reconnect to iTunes and sync again.

In some cases, your device may fail to sync contacts, calendars and account settings, or back up to iTunes. If this happens, reboot your device and re-sync.

FIXED: In some cases, syncing photos may result in only thumbnails on your device. If this happens, unsync Photos then re-sync again.

Xcode

FIXED: In beta 4, device restores using Xcode were disabled. This has been fixed. Device restores are now enabled and work in Xcode.

In some cases, Xcode 4.2 Organizer does not display a device that is in restore mode. As a workaround you can use iTunes to restore.

In iOS 5 beta 5, iOS Simulator is not compatible with previous releases of the iCloud Developer Seed for OS X. It is highly recommended that you update to the latest iCloud Developer Seed to ensure compatibility.

iOS 5.0 SDK supports both iOS 4.3 and iOS 5.0 simulators.

NEW: Xcode fails to build a Page-based template. You can work around this issue by adding the Core Graphics framework to your project.

Apple now selling unlocked GSM iPhone 4 in US, starting at $649

Apple updated its online store on Tuesday to begin offering unlocked models of the iPhone 4, starting at $649. Both the white and black versions of Apple's bestselling smartphone are available, with the 16GB and 32GB versions selling for $649 and $749, respectively, in the U.S. Apple online store. The device is not eligible for international shipping. Currently, the black versions of the unlocked iPhone 4 are estimated to ship within 1-3 business days, while white versions are listed as shipping within 3-5 days.

"The unlocked iPhone 4 requires an active micro-SIM card that you obtain from a supported GSM wireless carrier," Apple notes on the product description page. As with unlocked iPhones sold internationally, the device will work on all Apple-supported GSM networks around the world. Apple also takes care to note that an iPad 3G micro-SIM card will not work in the unlocked iPhone 4. In the U.S., customers with unlocked GSM iPhones can choose from AT&T and T-Mobile, though data transmission on the T-Mobile network will occur over the slower EDGE protocol because the carrier's 3G network is incompatible with the iPhone. Over the weekend, reports emerged that Apple would begin sales of the unlocked iPhone 4 in the U.S., though the device went on sale a day earlier than sources had suggested. On Monday, various outlets noted that unlocked iPhones had been shipped to Apple Stores with a price tag of $649 and $749. The release of an unlocked iPhone 4 comes as a blow to AT&T, which held an exclusive on the iPhone in the U.S. for more than three years, up until the release of the iPhone 4 on the Verizon network in February. The iPhone 4 has quickly become Apple's bestselling iPhone. iPhone sales grew 113 percent year over year in the second quarter of fiscal 2011, reaching a record high of 18.65 million units. According to Apple COO Tim Cook, iPhone sales were "off the charts in the U.S" with 155 percent year over year growth, driven in part by the addition of the Verizon iPhone 4.
