The T-Mobile myTouch 4G is a smartphone released by HTC at the end of 2010. It is the second 4G smartphone released by T-Mobile. It has a 3.8" TFT Super LCD screen, which allows for a 800:1 contrast ratio and a wide viewing angle of about 160 degrees. T-Mobile replaced the standard search button found on most Android phones with T-Mobile's Genius button. When pressed, this button opens up a voice command application that can be used to make calls, write text messages or emails, or to search the internet. The myTough 4G also comes with an 8 GB microSD card for extended storage.
