T-Mobile turns on 3G coverage for unlocked Apple iPhone models in some areas
dialing *#0011# on Samsung phones, certain T-Mobile branded handsets can use this spectrum now. These models include the Samsung Galaxy S and Samsung Galaxy S II handsets and the Samsung GALAXY Tab tablets. Other devices that can use the frequency include the HTC Radar and the Huawei Springboard.
With the use of a hardware unlock and the micro SIM cards just recently offered by the carrier, over 1 million unlocked Apple iPhone units are using T-Mobile's network. This is more the result of Apple selling unlocked units in the States and not a sign that the carrier plans on immediately offering Apple's smartphone. Besides, the 1900MHz frequency is being supported by T-Mobile only in some areas in order to reach the 84Mbps peak it is aiming to achieve next year. For the Apple iPhone to get consistent access on T-Mobile, Apple would have to add 1700MHz 3G to the iPhone 4S. Perhaps we will see a T-Mobile branded Apple iPhone in 2012.
