A:Answer The phone works on any network, so you can purchase it at the full price and send to you friend, but they would have to figure out how to get it activated. If you buy it outright at the full price, I think you can get it unlocked. I believe if you buy it on a payment plan through AT&T, they will not unlock it for you until you have the phone fully paid off which could take 24 or 36 months. It seems to me that you want to buy it on a payment plan. If that is the case, your friend would have to have AT&T service for it to work.
There is a finance option through Apple directly, and you get an unlocked phone right out of the box. This would give your friend to activate the phone on any network right away. I would ask a best buy expert if they have this option also.
