An Android phone from HTC and first offered by Sprint. Introduced in May 2010, the EVO was the first Android to feature 4G WiMAX service. With a high-res 4.3" screen, two cameras and slick UI features for its time, the EVO was a huge hit. The EVO Shift model was slightly smaller with a secondary, slide-out physical keyboard. See HTC G1, HTC One and HTC.
