Okay so here's my situation.. on preorder morning, I was ordering from my iPhone 4 Apple Store App and on my computer at the same time, in case one of them ended up not working. So it ended up working on my computer first, and great I just got my iPhone 5 today. But the day after I preordered that one, I opened up the app and was just messing around to see what would happen, and it let me buy two iPhone 5 32gb at the 2-year contract price of $299. So now my second one will be coming on October 5th. Now when I was setting up my iphone 5 just now, when it went to activate it, my phone number showed up on the screen, and below it said something like "If this is not the number you wish to set this up on, contact AT&T after activation." It also said if this is not the number you purchased your iphone with call Apple at this number. So my question is, when I sell it on eBay, will the buyer be able to activate it on their phone number okay? Or is there a way I could call apple to have my phone number unassociated with that iPhone via serial number?? I'm not worried about them activating the phone on my number because it asked for my billing zip and SSN after i confirmed my phone number during activation, but will they be able to activate it under their phone number via apple or AT&T fine? Any help would be great!
