I just bought a 16gb iPhone to upgrade my 8gb iPhone. I was under the impression I could just put my old SIM in there and not have to get into another 2 year deal thru iTunes...But up hooking it up to my computer, it gives me the original iPhone screen I saw when I first set up my 8GB. It wont let me just send my 8gb iphone's backup information to this new 16gb iPhone....What gives? What am I doing wrong? I dont want to sign a new 2 year contract....And this is the old gen iPhone...
