I'm exactly where you are on that one. I'd imagine that Apple will convince them to do it since AT&T will, I'm guessing on this one, charge $25 a month for unlimited 3G vs $20 for unlimited EDGE. That and Apple wants you to get the new one because you'll be able to use iTunes and the App Store wherever you want and that'll get Apple some more money...
excuse my denseness! Are you both suggesting that ATT MIGHT offer a $200 subsidy for current iPhone owners if the owners extend their contract another 2 years (but keeping their current iPhones)?
Buying a new 3G iPhone w/ subsidy is then another matter altogether.
