ATT doesn't provide 3g to 90%+ of Americans either...
And frankly, based on speeds, neither does Verizon or Sprint.
They all 3 do provide much better speed's than GPRS to most customers though. T-Mobile doesn't even have EDGE national yet so when the poor frequency 3G fall's back to the lesser poor 1900mhz GSM, many customer's are left with poor GPRS signal. -- 2010 Ford Fusion Sport
