So my family has AT&T as their phone carrier. I don't have a phone yet, but i did have an iPhone for a while just to use as a touch with enhanced capabilites, but i sold it to buy the 3G. If the 3G ones do indeed become unlocked, would it be best to just buy a service with AT&T or just buy a cheap phone without 3G. The stupid thing is i don't care about 3G or Edge i just want the iPhone, i don't mind using it as a normal phone without internet everywhere. So the question is, is it cheaper just buying a cheap phone and plan and unlocking the 3G and placing my AT&T sim in there. Or buying it directly from apple/at&t without unlocking. Am i always subjected to buying a unlimited data plan? I want the cheapest plan, but still have an iPhone? its kinda stupid... but its the iPhone... Since my family is getting a new family plan i just thought it would be good to get the right info down.
