Have you read the upgrade guide? (see my sig) If you see some Q/A missing, please let us know.
I read it, I just wasn't sure about my understanding and the process
The account holder or an authorized contact need to place the pre-order on the line that is eligible for upgrade.
The micro-sim arrives blank. Yes, just activate via iTunes.
This is the part I am still a little unsure about... I am an authorized contact but not eligible, but my father (whose upgrade I am taking) is eligible, so should it be billed/ shipped in his name? I do not understand how they know if I am eligible or unless it is tied in some way to the number which is eligible. Do they just make sure there is an eligible number on the account whose contract will be extended, and the phone is not really important. And since the sim card is blank, do i just activate it via itunes using my number or do i have to use his, since it is eligible and then go to ATT to get them switched?
Thanks again!
PS: as for the guide, I would just say a little expansion on the "using someone else's upgrade" section could use more explanation since many people are in a similar situation as mine.
