HTC EVO Shift 4G
The HTC EVO Shift 4G is an intermediate release in the EVO series. It's a phone aimed at the entry level market and while it may not be as powerful as its predecessor, it's no less deserving of its name. The EVO Shift 4G is essentially Sprint's version of the Desire Z, with HTC Sense running on top of Android and a full slide-out QWERTY keyboard.
The Shift also has 4G radios inside, a necessary component to a phone that's part of their flagship lineup. The HTC EVO Shift 4G has been available since January 9th, 2010.
