Please forgive me for posting this question regarding an iPhone in this forum. I posted this question in the iPhone forum but have not received any answers. I am asking here because of its vast pool of knowledge and I believe the same question would apply to iPads.<br><br>AT&T sent me unlocking instructions, below. Basically go to iTunes
and do a backup and restore if I understand correctly. I upgraded from a 3Gs to a 4S whose info is on iTunes. If I connect the 3Gs and do the
restore will it mess up my 4Gs info?<br>
