I updated it the day it came out and it has totally messed up my phone. Every 15 minutes it restarts and it's very frustrating as I'm always on facetime to my boyfriend who lives far away. I've tried twice to reset my phone to the "new iphone" default and it's still doing it. I've tried turning it off and on multiple times, I've tried a lot. I don't know what to do, as I'm not technical at all and a lot of the advice that has been given to others I haven't been able to follow. Any help?
