Today MetroPCS announced that seven markets will receive EV-DO-based 3G. MetroPCS won the 3G spectrum in 2006’s AWS auction. Three existing markets, Detroit, Dallas and Los Angeles, will see their service upgraded to EV-DO from 1xRTT. MetroPCS is also launching four brand new markets with 3G. They are Boston, Las Vegas, New York and Philadelphia. The EV-DO 3G network will allow MetroPCS to offer more advanced data services, including unified communications and video mail. MetroPCS did not provide a timeframe for the 3G roll-out.
