Just called both the Apple store and local AT&T store. They both said that you could do an upgrade swap at an Apple store but they would have to call the AT&T customer service center to do the swap, which might take more time. But I'm okay with it.![]()
I just called the Arden Fair Mall Apple store in Sacramento, CA -- they said they cannot do an upgrade swap by calling AT&T.
It seems like any questions beyond "Will you have iPhones on Thursday" will get you different answers from both AT&T and Apple employees.
