If you are a T-Mobile user, and are waiting for the expansion of their 4G network, and happen to live in Las Vegas, New York, or Orlando good things are coming your way. T-Mobile has announced that they are turning on their 42Mbps network in these three specific areas first, closely followed by more locations as well.

“As T-Mobile continues the aggressive expansion of America’s Largest 4G Network, we’re doubling our maximum speed in more than two dozen markets, starting with three important cities today,” said Neville Ray, chief technology officer, T-Mobile USA. "We will continue to build on our 4G network advantage this year, providing customers with an industry-leading mobile data experience.”

While unfortunately this doesn't help everyone, it is certainly a big step in the right direction for those with T-Mobile, and by mid-year T-Mobile is expecting to have 4G speeds in 25 markets, which would cover over 140 million people. [BusinessWire]
