as AT&T subsidize the phone, over a two year period, which brings the price down.
No service means you will pay full price for the phone and that's not cheap
can i buy an iphone and not sign up with at&t and still use it like a touch. will it still get wifi through a hot spot? the reason i want to do this is i want a touch with a camera. and i dont want to wait for the touch with a camera.
