Currently, Sprint is the only U.S. mobile operator that promotes having a 4G network and offers 2 handsets that are enabled for use on the pipeline-the Samsung Epic 4G and the HTC EVO 4G. T-Mobile has recently launched its first HSPA+ enabled device, the T-Mobile G2, which can handle speeds up to 14 Mbps, and has announced that it will release the T-Mobile myTouch 4G on November 3rd.
The carrier's HSPA+ network currently tops out at 21 Mbps, nearly double what Sprint is claiming for its WiMax 4G service. T-Mobile is continuing to upgrade its broadband network and is expected to double its speed to 42 Mbps by next year.
All of T-Mobile's current Android lineup and 16 of its current 3G models are compatible with HSPA+. The number 4 carrier in the U.S. currently offers its faster service to 100 million people and hopes to double that by the end of the year.
