I have been with T-Mobile and Verizon for past iPhone releases. I switched to AT&T recently, and plan to remain with them for the 6S. My question is: Last year, on the Apple Store, were you able to order an upgrade for your current AT&T phone at full price? I want to pay full price and not use any Next plans or anything like that. If not, were you able to do so via AT&T themselves?
