https://www.att.com/deviceunlock/client/en_US/ I've been to that site and pretty much understand what I would need to do. However, would the order and re-signing of a new contract immediately invalidate the previous contract and equipment. Thus, the phone can be unlocked. Or, do you have to wait until you physically switch the phones before you can? Lastly, is any of this even possible? Or is this just 2+ customers?
