★★★İOS5 BETA4 Çıktı Buyrun :)★★★

Accounts 
  When creating an iCloud account you can use any Apple ID provided it is a full email address and not a MobileMe account. If you have a MobileMe account, you can copy data from that account to an iCloud account to use during testing. 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. 
  It is recommended that you disable Bookmarks on multiple accounts. If they are enabled, the results might be undefined. 
  FIXED: In this beta the option of “Choosing a security question” is not working during an iCloud account setup. 
   
   
   
  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. 
  Switching into AirPay Video while using mirroring will leave the screen black but the video is still playing. 
   
   
  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 
  All MobileMe calendars were duplicated after turning calendar syncing off and back on. 
  FIXED: Restoring from a Seed 1 backup or earlier will cause MobileMe/iCloud calendars not to sync. Subscribed calendars will show up in Calendars but none of your event calendars will appear in MobileCal. To workaround the problem please remove and re-add the account. 
  If SnowLeopard isn't syncing your calendars on iOS device and you created a calendar or reminders list using a previous iOS 5.0 seed, change the name of that calendar or list on the iOS device and then let it sync. 
  In this beta Birthday calendar is temporarily disabled for Web apps and Windows and will be available in a future release. 
   
   
  Contacts 
  NEW:In MobileMe local contacts are deleted instead of be being merged. 
  In this beta Import/Export vCard is disabled from Action menu and will be available in future release. 
  There is no new build for AppleTV for beta 4. Please continue using the build provided with beta 3. 
   
   
   
  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 suggest you also manually back up your device with iTunes. It is strongly advised you upgrade to this version of the iOS 5 beta in order to continue backing up your devices and preserve previous backups. 
   
   
  iMessage 
  NEW: iMessage beta 1 will be unable to communicate with iMessage users on beta 2 or later. 
  iTunes 
  The version of iTunes that comes with beta 4 cannot sync devices that have the beta 2 software installed. To avoid this problem, do the following: 
  Sync any devices that have beta 3 installed to the version of iTunes that came with beta 4. 
  Upgrade iTunes to the version that comes with beta 4. 
  Connect the device and install the beta 4 software. (Understand that you might see a failure to sync error when you first connect the device.) 
  After installing the beta 4 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. 
   
  Mail 
  NEW:Forwarding a message with attachments included does not attach the file and the message compose screen does not change from "Loading...." 
   
   
  Music Library 
  NEW:Some songs are missing their album artwork after changing the device library via syncing. 
   
   
   
  OTA Software Update 
  NEW: If you are doing a OTA software update from beta 3 to beta 4, you will need to re-sync your photos with iTunes." 
   
   
  Personal HotSpot 
  NEW:In this beta iPhone 4 device cannot join personal hotspot even if it is on due to a non functional WiFi tethering on these devices. 
   
  Photo Adjustments 
  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. 
   
  WiFi Syncing 
  In iOS 5 beta 4, wireless syncing is now available on Windows as well as the Mac (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. 
  NEW:In some cases, syncing photos may result in only thumbnails on your device. If this happens, unsync Photos then re-sync again. 
   
   
  Xcode 
  When uninstalling iOS 5.0 SDK beta 2 or upgrading from iOS 5.0 SDK beta 2 your new install might be missing the /usr/lib/libsvn* files thus making some subversion functionality (such as the perl bindings and git-svn) unavailable. 
  If your host machine is a Snow Leopard based, you can get these back by reinstalling BSD.pkg from your OS DVD, followed by a Combo Update to Mac OS X 10.6.8 or later. 
  If your host machine is Lion based you will have to reinstall the OS. 
  In this beta, device restores using Xcode are disabled. Please use iTunes only to back up and restore your device. 
  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 4, the 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. 
   
   
  Settings 
  FIXED: In this beta FaceTime icon is missing in Settings on the iPhones. 
  Simulator 
  NEW: 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. 
  NEW: 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. 
   
   
  Twitter 
  NEW: 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.
