What I mean is, will I be able to buy a disposable AT&T GoPhone/Pay As You Go cellphone, and swap that SIM into my iPhone, will it work?
I heard that you need to Jailbreak it to do this. What exactly does
Jailbreak-ing it do?
And in case this doesn't work,
1. I heard you can cancel an AT&T contract within 3 days of Activation and pay no fees and also get your activation fee back, based on AT&T policy. Will the iPhone still work after this, just without Phone capabilities?
2. And what is the cheapest possible iPhone plan? Does it work on the $10 family plan on AT&T? What about another AT&T SIM not on a GoPhone plan?
