Ok so, My wife is eligible for a upgrade, She is not into the whole iPhone craze, So i upgraded her line and will be using the iPhone 4 on my line. The iPhone has already been ordered thru ATT ( at 8am day of launch ) Now my question is, When i receive it, I cant simply put my sim card in since they have these new Micro-Sims and if i turn the phone ON, I will assume that it will activate her line, which will deactivate her sim in her current phone? So my question is, What steps do i need to take once i receive the iPhone? Do i need to call AT&T and give them the Sim iPhone serial? Sim card number? etc? ( please say it aint so! I do not want to be anywhere near ATT come the 24th, lol ) Do i leave the power OFF on the phone? Normally ( back in the day, lol ) A new phone would arrive, I would pop out my SIM and put it into the new phone and thats it but i cant do that in this case.
