Well, Sprint will, without a doubt, have a pile of markets that will be announced as "live" by the time the iPhone is released (even if the city is only 10% complete). The iPhone will still do 3G, have unlimited data on Sprint and have the promise of LTE coming. I don't think Sprint will have much problem selling iPhones. They may not draw the new customers that they did with the 4S, but most people that buy iPhones have no idea what 4G even is and won't even figure out that their data speeds aren't what was advertised. The only thing Sprint has to worry about, IMO, is getting Apple to put LTE on the Sprint version of the iPhone.
