Find My iPhone

• After OTA update Find My iPhone does not work. To make it functional you can toggle the the Find My iPhone from OFF to ON in Settings.

GameKit

• NEW: Auto-matching with the Turn-based view controller does not work. Invites or the direct auto-match API can be used as a workaround.
• Match data for turn based matches is currently limited to 4 KB of data.
• FIXED: Events will be passed to the delegate whenever a turn is made on a match, instead of just when it becomes the local player's turn.

iMessage

• iMessage beta 1 will be unable to communicate with iMessage users on beta 2 or later.
• FIXED:Setup Assistant does not provide AppleID password as an input for the FaceTime in iMessage.

interface Builder

• FIXED: When editing the value of a constraint in the inspector, the constraint remains selected, and the outline view continues to show the constraint as selected.
• In XCode 4.2 when copying views (either a single view or multiple views), both the user defined constraints directly on the selected view and the user defined constraints between the views being copied are copied to the pasteboard.
• Changing the segment style of an NSSegmentedControl object to “Automatic” might crash in documents using Cocoa Auto Layout. To workaround the issue use an explicit segment style such as Round or Textured, and at runtime, change the segment style to automatic using the setSegmentStyle: method.

iTunes

• NEW: When trying to restore an iPhone 3GS or iPod touch 3rd generation device running Beta 6 to Beta 7 using iTunes, you will have to set the device into DFU or you can OTA update to Beta 7. To enter DFU mode you will have to:
  1. Connect the device to USB on your Mac.
  2. Turn the device off.
  3. Launch iTunes on your Mac.
  4. Hold down the Home and Power buttons for 10 seconds.
  5. Continue holding the Home button but let go of the Power button.
  6. Hold Home button for 13 seconds or until the device shows up in iTunes.
• The version of iTunes that comes with beta 7 cannot sync devices that have the beta 6 software installed. To avoid this problem, do the following:
  1. Sync any devices that have beta 6 installed to the version of iTunes that came with beta 6.
  2. Upgrade iTunes to the version that comes with beta 7.
  3. Connect the device and install the beta 7 software. (Understand that you might see a failure to sync error when you first connect the device.)
  4. After installing the beta 7 software, restore from your the backup you made in step 1.
