Alright, here's my situation: I'm under 18 and on my mom's Verizon plan, which I think expires later this year, though I'm not sure. I want an iPhone (don't we all?), but I'd be the only one with it. Is there a way to get a plan going with AT&T once the Verizon one expires with her non-iPhone being the main phone in the plan (if there is such a thing) and my iPhone? How would that work? And will iPhone registration/stuff work for me being under 18? Can I do it with my regular Apple ID or do I need an iTunes account, which requires a credit card, which I don't have? Thanks for your help.
