"Additionally, Reuters reports that AT&T has said that purchasers who do not activate their iPhones within 30 days will be subject to penalties. No details on these proposed penalties have been made public."
First it's reported that they must be activated in-store. If there are penalties for not activating within 30 days, this has to be assuming that the phone is purchased, and then activated at a later date (a.k.a. not activated right at purcase, in the store)... right? What's going on here, which is it???
I think waht is going on here, is since AT&T is subsidizing the phone. they may be taking the stance that if you do not activate your phone, you will be automatically charged (and taken to collections) for the price of the full phone, and then they may put a block on the FCC CAP# preventing it from being able to be activated anywhere else. But if you do want it activated through AT&T, they will not let you until the penalty is paid.
kinda like what Sprint does, if your payment lapses or you cancel your contract you are charged an early termination fee. then you cannot re-activate your phone without paying the fee and a re-connection charge.
This may not be apple's doing ,but may be AT&T's.
