Okay, so here is my situation. I'm not asking to get an iPhone brand spankin' new with no data plan; I know that's like pulling some serious teeth. So... I have an iPhone 3G that was purchased almost 2 years ago, aka it's well beyond eligible for an upgrade (since at&t allowed upgrade eligibility for iPhone 3G owners @ the 3GS release), and I plan on getting the 4G iPhone next month or so when it's released. Now, my iPhone is on a family plan with two other lines on it, one being my mother's. She said she would love if she could have my iPhone 3G when I replace it with the new iPhone, but she refuses to do it if forced to pay the data plan. So, simply put, is there a way to "cancel" my current iPhone line and her line or whatever trickery needs to be done, and then have the iPhone 3G essentially replace her current cell phone? I imagine it may be possible, as I've read that some have cancelled their iPhone contracts and then added another line to a family plan and doing some stuff with SIM cards in order to have an iPhone w/o data, but this situation may be different, I'm not sure.
