I still don't see the appeal. The Iphone 3GS is now $50 at AT&T. Prepaid data plans suck, so even if going with out a monthly plan, costs don't work out that much better. A $200 subsidized iphone4 is better than an unsubsidized $200 cheap phone that will probably need to be upgraded in a year anyways. If you upgrade your phone that much, then I don't see why buying a cheap low grade iphone is a good idea.
