Yesterday T-Mobile announced that they are expanding their 4G like speeds on their HSPA+ network in the Northeastern US and other large cities around the country. AndroidGuys added that T-Mobile's HSPA+ network is a 3G network that has theoretical speeds of 21Mbps, which surpass Sprint's 4G network.
Here is a snippet from the press release from the T-Mobile Forums regarding the new regions that will be covered by the HSPA+ network:
As the company continues to aggressively broaden its HSPA+ network in the New York City metropolitan area, including New Jersey and Long Island, T-Mobile announces the further build-out and widespread availability — right now — of its super-fast network in adjoining regions, including Upstate New York (Albany, Buffalo, Rochester and Syracuse), Connecticut (Hartford, New Haven, Milford and Stamford) and Providence, R.I. Already live in Philadelphia, as well the Washington, D.C. suburbs, T-Mobile’s HSPA+ network will expand into Boston and Washington, D.C. in the coming weeks, further enhancing the Northeast corridor with 4G speeds.
In addition, customers in Memphis, Tenn., and Las Vegas, also now can stay connected on T-Mobile’s high-speed mobile broadband network.
One of the undeniable benefits from T-Mobile's HSPA+ network is that it should work on many already released 3G phones (which according to Phandroid, will include the myTouch Slide 3G, Garminfone, and possibly the Nexus One), and that unlike Sprint, T-Mobile will not charge extra to access the increased speeds, or have to purchase new 4G compatible phones to take advantage of the network.
