Just a quick heads-up: Apple just dropped iOS 5 beta 3 to developers. Jailbreakers and especially unlockers, should stay away from beta 3.
- 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 remove and re-add the account.
- iMessage beta 3 will be unable to communicate with iMessage users on beta 1. It works between beta 3 and beta 2.
- Modal alerts don’t appear for iMessages.
- In this beta FaceTime icon is missing in Settings on the iPhones.
