So I got a brand new iPhone 5s today, and I'm trying to activate it, but when I plug it into itunes, it just gets stuck on the screen telling me to connect it to itunes. It gives me the hello screen and the language and Wi-Fi screen, then after, it just won't get off the itunes screen. I've tried restoring the information from my old iphone 4 onto it multiple times, I've tried restoring the phone itself, nothing works. Apparently I'm supposed to get more screens after that ask for apple ID stuff, but it just won't leave the connect to itunes screen. It came with a new SIM card, but I'm pretty sure it's just the same number. I thought I could activate it from home, but do I need to go to the AT&T store and let them do it? My old iphone 4 was messed up to where it wouldn't let me updat from 4.3.3 firmware, so I'm not sure that's a problem as well. Any help please?
