Hi, I am planing to upgrade my iphone 2g to 3gs this Friday. However, the account name is under my dad's name and his bank account. He is out of the country right now. My question is, do I have to show them any identification when I go buy the new iphone either by in store or online order? If I buy the 3gs through upgrading in my ATT account, do I have to show them any identifications? Or by ordering it through ATT account is identification, and I can just go pick up the iphone at the store? Also, is it to late now to pre-order and get it by the 19th? Thanks for your help.
