So I'm receiving an iphone 4 in the mail on Tuesday that I pre-ordered from apple.com. But what if I never open the box and plug it into iTunes? What state is the phone in? Is it tied to my account already in the box? I checked my account on att.com and they've already reupped my contract, which is fine considering I got the subsidized pricing. But what if I never switch over and I just continue to use my 3gs? Could I sell the unopened iPhone 4 to someone else or does Apple somehow preload my account information onto the phone they're shipping me? Thanks!
