I've got a friend with an Evo, and both the Sprint store and his home show to be in a 4G service area. Home is supposed to have the 'best' coverage, and the Sprint store is supposed to have 'good' coverage. Neither location has ANY usable 4G coverage on the Evo. It cuts in and out with barely any signal at all, confuses the phone and never gets data easily until you turn off 4G. BTW the 4G adapters for computers work in both locations, albeit with low signals. The Evo, unusable. My friend went to Evo training and asked about the non-existent 4G coverage. The trainer said that all they can say is 'we can't guarantee 4G, 3G or 2G coverage.' WOW, that sounds just like AT&T when I had the iPhone 3G.
