Ok I have a 3g and I am on my own plan. My parents also have At&t and they have a phone upgrade in June. I am wondering if At&t will let me buy a phone using the upgrade discount on her line, and then give her my iphone (to use as a touch she doesnt want to pay for the data plan) and she can go back to using her old phone, and I will be able to use the iPhone on my plan. Has anyone done this? Does this make sense what I am asking. Any help would be awesome. Thanks in advance.
