I am using my moms upgrade eligibility to get an iphone 5 for my girlfriend for christmas. I will not be turning the phone on as it can cause problems with the swap process. What I am wondering is: - When I call ATT and have them do the swap to my girlfriends line, will her old iphone 4 be deactivated right then and there? Or will it deactivate when she turns on the iphone 5 and does the activation on the phone on christmas? - And I plan on buying the iphone 5 from Best Buy and have it "not activated" when buying it. I can still have ATT do the upgrade swap even though I bought it from Best Buy, correct? I tried getting a hold of ATT, and was unsuccessful today, so I wanted to ask here. Thanks in advance.
