iOS7 beta 2 (iPhone 4) -iMessage does not activate, sends text rather than iMessage. -time zone took 20 minutes to adjust. iOS7 beta 2 (iPad mini) -Battery remains 100% percent after minutes of usage -rotation takes a little but longer than ios 6 Other than iMessage and time zone, it's great I love it so far. Just want this iMessage activated Troubleshooting Steps I've done: Reset all settings (not content) on iPad and iMessage asked to log in with email and ever since it worked. Does not seem to be working on iPhone though. Post if you have any issues, maybe we can all help each other.
