I currently use Verizon and my friend offered me his 3G iPhone for $50 as he's getting a 3G S. I would like to dump Verizon and buy his 3G, but Verizon has a $200 cancellation fee so I'm stuck with them for six more months. Could I use the iPhone for data (via wifi) and music/videos (basically like an iPod Touch) without setting up a plan until my contract with Verizon runs out?
