Why can't the Sprint HTC Evo operate on Verizon? Is it the WiMAX vs. LTE that is the hitch? Could an unlocked Evo function on VZW? I would appreciate someone explaining this. I already have the Eris and a Moto Droid now and am considering the Incredible but the Evo is really what I want. The early termination fees and hesitation about Sprint's network are considerable roadblocks for me. Thanks!
