Ive had my iphone for awhile now. I have all contacts, sms, picture, ect on the phone already. If i register my iphone for the first time will it loose all my information thats already on my phone? I plugged it in and its asking to register as a new phone. I didnt push it because ive accidently erased my phone plenty of times. How do i register my phone without loosing my info that already on it?
