Just thought of this. What if Apple keeps making the 3Gs and aims it at the prepaid market? It will still have all the powerfull features of the iphone just not everything the newer generations have. They could even rename it the iPhone nano or something.
Of course if someone wants the new iphone they will need sign up for a 2 year.
