Keep in mind, that spec wise, except for the type of processors and such, they are the same (bluetooth, gps, wifi, camera, etc. ) but the radio's is where it'll be the game making difference.
ATT will only support quad band/UMTS, where Verizon supports not only the dual band CDMA with rev 0 and A but also Quad band as well and UMTS making it more feasible for someone who really wants to globe trot around with a phone that will work anywhere with any network.
So i would say Storm 2 if you want a touch phone, but i'd say compare the bold 9700 with the tour 2!
thank god im getting BOTH!
