So my iPhone's contract runs out in February. Sure, when it ends I could just get the 3GS with the subsidized price that I would still receive from buying the first one, however, I really don't want to get one in February when a new one would be coming in June. (More than likely.) My question is, what do I do? Would I be able to stick with this one until June or so? For instance, could I renew my current contract for 6 months? Do I get some cheap flip phone to keep me on AT&T, so I still get the subsidy on my next iPhone? What should be my next move?
