Apple has released iOS 5.1 beta 2 to developers. The update comes exactly two weeks after the company seeded the original version of the iOS 5.1 beta.

The new software is expected to feature a number of bug fixes and additions, including a sufficient patch for the long-time running battery bug and a rumored Siri enhancement. We’ve got the full change log…

Notes and Known Issues
The following issues relate to using the 5.1 SDK to develop code.

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 at:

• The NSNetService class and CFNetService APIs do not include P2P interfaces by default. To browse, register, or resolve services over P2P interfaces, an application needs to use the Bonjour DNSService*() APIs noted below.
• Setting the interfaceIndex parameter to kDNSServiceInterfaceIndexAny in the following API’s will not include P2P interfaces by default. To include P2P interfaces, you must now set the kDNSServiceFlagsIncludeP2P flag when usingkDNSServiceInterfaceIndexAny or set the interfaceIndex to kDNSServiceInterfaceIndexP2P. The affected APIs are:

  • DNSServiceBrowse
  • DNSServiceRegister
  • DNSServiceResolve
  • DNSServiceRegisterRecord
  • DNSServiceQueryRecord

FIXED: App icons and profile photos are not loading in apps using Game Center.

iCloud Photo Stream
NEW: Photos taken using iOS 5.1 can be deleted from Photo Stream on your device and will be removed automatically from Photo Stream on your other iOS 5.1 devices. Older photos can be manually deleted from your iOS 5.1 devices.

iCloud Storage
• Provisioning profiles must be enabled for iCloud in the iOS Provisioning Portal. To enable a provisioning profile for iCloud, navigate to the App ID section of the iOS Provisioning Portal and configure your App ID for iCloud. After enabling the App ID for iCloud, regenerate your provisioning profiles to enable them for iCloud.
• The setSortDescriptors: method of NSMetadataQuery is not supported.
• In iOS 5, files that are protected via Data Protection cannot be used with iCloud Storage APIs.
• File names are case-insensitive in Mac OS X but case-sensitive in iOS. This can lead to problems when sharing files between the two using iCloud. You should take steps on iOS to avoid creating files whose names differ only by case.

Movie Player
Starting in iOS 5.0, in order to facilitate finer-grained playback control, a movie player is not automatically prepared to play upon creation. Call the prepareToPlay method to prepare the movie player. For more information, see MPMoviePlayerController Class Reference

Music Player
Using shake-to-shuffle causes Music app to freeze and playback to stop.

In iOS 5, signing certificates with MD5 signatures is not supported. Please ensure that certificates use signature algorithms based on SHA1 or SHA2.

Setup Assistant
NEW: Immediately after completing the Setup Assistant, it may re-appear and show the wifi screen and/or final “Thank You” screen. The workaround when in this loop is to reboot the device.

SpringBoard Lock Screen
NEW: The lock screen can intermittently get in a state where double-clicking the home button will no longer bring up the camera button. To get out of that state, you need to restart the device.

As you can see, Apple finally added a way to delete Photo Stream photos without having to reset anything. Any photos take with an iOS 5.1 device can be deleted from Photo Stream individually.

iOS 5.1 beta 2 is available now for the iPhone, iPad, and iPod touch to folks with developer accounts. Be sure to let us know if you notice any other major changes in the update.

  • So glad they finally added a way to delete individual photos from photostream. Maybe now I’ll actually turn the photostream service back on.

  • Hey guys, i have an iphone4 factory unlock ios 4.1 jailbreaked
    Every time i try to restore to a newer version (4.3.3 per ex) i received an error 3194 in itunes
    Can somebody help me to upgrade my iphone
    Tx a lot

    • you can update only to 5.0.1 because you don’t have the SHSH blobs for 4.3.3 and Apple is no longer signing so old firmware.

    • you can update only to 5.0.1 because you don’t have the SHSH blobs for 4.3.3 and Apple is no longer signing so old firmware.

      • So theirs is no pb if i want to upgrade to ios 5.0.1? I won’t see this error?

        The best way to get yourself equipped with iPhone and Apple as a whole is to visit this site everyday. Just this morning the news about a valid jailbreak was posted on this blog. Come here everyday and you won’t regret.

        At the moment, there is no jailbreak. But there is one coming soon. I won’t even advise you to tether jailbreak your iPhone. Cos you will sure come back to ask more questions

      • Itopsi it seems u know what ur saying but is it possible i can’t upgrade per exemple my ipad1 on 3.2.2 to 4.3.5 for the same reason or can i with the i pad

      • There should be no error when you will trying to make restore to 5.0.1
        Hovever there is ONLY Tethered JB for now, wait about two weeks, there shoud be untethered JB by then.

        This applies also to iPad 1, iPod Touch 2nd/3rd/4th gen and iPhone 3GS/4 (not sure about JB for 4S & iPad 2)

    • You need to download de iOS 4.3.3 in the download section en iDB. Then open iTunes, and click in Restore+alt, search the .ipsw that you downloaded previously.

      If you received the error 3194 means that you save your SHSH with TinyUmbrella, go to this app, and click in Advance, uncheck “Set Hosts to Cydia on Exit (If you need a clean restore from Apple uncheck this box)”.

      Restore in iTunes for update your iOS.

    So, in the end, was the battery issue solved or not with 5.0.1? iPhone 4 specifically.

  • Anyone having mail app related issues like freezing, excessively long load times, and crashing? If so, any solutions available?

  • Here is something I came across when using the new version safari no longer open bookmarks whenever you open safari without a preopened page.

  • Anybody else noticing a smaller lock screen slider?

  • Anonymous

    It does not fix battery on the iPhone 4s and there are a lot of freezes in the music app

  • Is it just me, or is sending iMessages to earlier iOS 5 versions impossible from this update?
