Tmo's data is terribly slow. They do not seem to know that 3g or broadband is... When I questioned the PDA tech whether or not Tmo was going to pick up broadband like Cingular, her response was, "Well, with Cingular you drop a lot of calls, and if the speed is faster, you'll drop the calls quicker." I'm not sure if it was dry humor or stupidity, but regardless, VZW's is MUCH faster. Compare cable internet service to dial-up.
Just my opinion..
