So, it's not the antenna, but instead, I can't even open the phone app! I have to reset my phone and then I can open the app once. So each time I want to make a call, I have to reset my whole phone. This just started happening today, and the phone is 2 days old. Any advice? I don't want to do a full restore because I "restored from backup" from my old iPhone. I don't want to lose all those things!
