If I were to go into AT&T to buy one of the iPhones refurbished and i paid with a card would it be linked to me in any way. I planned to tell them I was buying it as a gift and that the recipient would come in to set up a new plan. Would it be linked to me if I actually intend to sell it. For instance if the person I sold it to called in about it, would they pull up it's serial or IMEI and show that I am the original owner? I just want to cover all bases.
