I am out of town and went to a local Apple store in Oklahoma (I was surprised as shit when I found out there was an Apple store in Oklahoma) and the servers were down so they had 2 lines, 1 for new customers and 1 for current customers. Well for the current customers they just asked to see your iPhone, scanned new phone, and you paid. You signed no new contract, and didn't ask for your wireless number . They said it will all be on itunes when I plug it in
