iMessage

• NEW: iMessage beta 3 will be unable to communicate with iMessage users on beta 1. It works between beta 3 and beta 2.
• NEW: Modal alerts don't appear for iMessages.

iTunes

• The version of iTunes that comes with beta 3 cannot sync devices that have the beta 2 software installed. To avoid this problem, do the following:
  1. Sync any devices that have beta 2 installed to the version of iTunes that came with beta 2.
  2. Upgrade iTunes to the version that comes with beta 3.
  3. Connect the device and install the beta 3 software. (Understand that you might see a failure to sync error when you first connect the device.)
  4. After installing the beta 3 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.

MMS

• Sending an MMS of large videos does not work.

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.

Reminders

FIXED: The Reminders application does not send notifications for reminders that are based upon the entry (and/or exit) of a location if there is no date associated with the reminder.

Settings

• The “Back Up Now” button is enabled without the backup data class being enabled for the account.
• FIXED: If you bring up the keyboard of the terms in Settings->General->Software Update, you cannot dismiss it. You have to force quit Settings to get out.
• NEW: 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.
