hi i just recently bought an ATT tilt, it is a great phone. Dont ask me why, but i need to get rid of it for my own reasons. My parents are upgrading their phones in a week and i was wondering if when my dad gets his new phone can i take that one and give him the tilt? He is getting a blackberry if that helps. Are there any complications in the plan that will prevent me from doing that?. Please i need advice from only someone that knows what there talking about thankyou.
