I spent 2 hours one day and 1 hour the next day with apple support and not sure what fixed it, but mine works now. Sorry I cant tell you for sure, but we did turn off imessage and facetime, then turned imessage back on. also I change the the sound and vibrate to different ones from the default ones. Good Luck!I have the same issue on my S1. Were you able to get this fixed?
