Bear with me now, iPhone noob here . Im planning on getting one but a few things are in the way. I already have a plan with tmobile and want the iPhone for internet mainly and wouldn't mind having texting. But I don't wanna pay for AT&T's crazy contracted plans. Do i have any options? I've heard of buying an unlocked one, will using a prepaid sim card to get the unlimited data plan work? How would I go about this, any thing would help!
