If you have a current iPhone, and a new model comes out, what are people going to do? 1) Is Apple/AT&T going to force people to extend a contract with the new phone? They shouldn't since there is no dicount on the phone with a subscription, unlike other phones... but I bet they will require contract extension! 2) What will people do with their old iPhones? Who will buy them on ebay if they are not 3G? 3) Will the old phones still function as phone-less iPhones?
