I was happy to read that most were successful doing the att swap over the phone rather than going to an actual store. my senario: i took an upgrade from my fathers line (not on the same account) purchased from apple.com. I made sure I read all the threads about properly doing the swap, didn't turn the phone on until att told me to do so. I noticed on activation my fathers number came up so at that point I just stopped. ATT already changed my sim and imei to my number/account so they see me with an I5. Problem now is the phone is not activated and is looking to activate with my dad's number. After some research, seems purchases from apple need the phone activated with the original upgrade number for security purposes. I confirmed that this morning by getting a new sim from att and it still shows my father's number. That's fine ill see my father tomorrow, go to att and do the sim swaps. The problem now is that when att "switched" the sim/imei to my line I most likely will have problems activating even if I do it under his line. They're telling me that I have to somehow activate a new nano sim with my fathers line, pop that sim into the I5 and try to activate that way. Has anyone done this? If I call apple can they fix this? Next time I'm making all purchases through att.
