A leaked strategy document from T-Mobile has shown TMoNews that the carrier is actively trying to discourage the large number of unlocked iPhones on its network. Incorrectly referring to the devices at the "iPhone 4G" and "4G S," the staff memo insists that T-Mobile users are getting a "poor" experience by being on the carrier's EDGE (2G) network. Moving to one of its '4G' phones like the HTC Amaze 4G or Radar 4G will be free them from being "stuck in the 2G slow lane" with Apple's device.
