| iOS 5.1 beta bears a build number of 9B5117b and weigh in at 700 MB to 800 MB depending on the iPad or iPhone versions Includes:- iPad 2 (Wi-Fi) iPad 2 Wi-Fi + 3G (GSM) iPad 2 Wi-Fi + 3G (CDMA) iPad (Wi-Fi and Wi-Fi + 3G) iPhone 4S iPhone 4 (GSM) iPhone 4 (CDMA) iPhone 3GS iPod touch (4th generation) iPod touch (3rd generation) You must use iTunes 10.5 or later to install iOS 5.1 beta on your devices. iOS 5.1 beta is not available via over the air software update. Be sure to backup your devices using iTunes 10.5 or later or through iCloud backup prior to installing iOS 5.1 beta. After installing iOS 5.1 beta, you can restore your device using either iTunes 10.5 or later or through your iCloud backup. This version of iOS is intended only for installation on development devices registered with Apples Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state, which could necessitate an out of warranty repair. Devices updated to iOS 5.1 beta can not be restored to earlier versions of iOS. Devices will be able to upgrade to future beta releases and the final iOS 5.1 software. Release Notes: Notes and Known Issues The following issues relate to using the 5.1 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 at: Move APIs 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 APIs will not include P2P interfaces by default. To include P2P interfaces, you must now set the kDNSServiceFlagsIncludeP2P flag when using kDNSServiceInterfaceIndexAny or set the interfaceIndex to kDNSServiceInterfaceIndexP2P. The affected APIs are: DNSServiceBrowse DNSServiceRegister DNSServiceResolve DNSServiceRegisterRecord DNSServiceQueryRecord GameKit App Icons and Profile Photos are not loading in apps using Game Center. iCloud Storage Provisioning profiles must be enabled for iCloud in the iOS Provisioning Portal. You can enable a provisioning profile for iCloud by navigating to the App ID section of the iOS Provisioning Portal and configuring 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. Newsstand FIXED: Deleting an issue that was marked as the currently reading issue could cause a crash. Security In iOS 5, the signing of certificates with MD5 signatures is not supported. Please ensure that certificates use signature algorithms based on SHA1 or SHA2. Xcode/Developer Tools A bug in the documentation organizer causes an exception when you type in any field in the content area. To prevent the need to log in to the developer website from Xcode, download documentation sets locally using Xcodes documentation preference pane and enable the Check for and install updates automatically checkbox as a workaround. uninstall-devtools script mistakenly removes files and packages even if Xcode is still running. Be sure to quit any running copy of Xcode before starting the uninstall-devtools script. The Network Link Conditioner daemon cannot be launched after installing the Networking Link Conditioner without a reboot. You can manually workaround the issue with a restart or by the following command: sudo launchctl load /system/library/launchdaemons/com.apple.networklinkconditioner.plist.] In the iOS 5 development tools, it is possible to extract APIs used by an application and have them checked for use of private APIs. This option is offered when you validate your application for app submission. |
