Not to hijack the thread but I have a few question of my own. First I'll explain the situation.
I have a 3G and I'd like to upgrade to the new iPhone. I would like to use the upgrade from another line because mine isn't eligible until August. The other line is a BB, my dad's line. My dad would then like to use my old 3G.
So what is going to happen as far as SIMs go when this happens? When we use the upgrade will the SIM that comes with the iPhone HAVE to be activated with my dad's number and then switched over to my number somehow, or can they simply activate it with my number.
I foresee an issue where the SIM that comes with the new iPhone (a micro sim), is pre-activated with my dads number and then he's stuck with a micro sim he can't use in my 3G and I'm stuck with a mini sim I can't use in the new iPhone. Also, what happens to your old sim when you get an iPhone? Is it completely deactivated? Can it be reactivated with all the data still on it?
