HTC has just leaked the EVO Shift 4G model again, looking hotter than ever. This WiMAX handset is supposed to debut on Sprint in 2011 and we can see it sports a very appealing sliding QWERTY keyboard with 4 rows of keys and a nifty pad on the right side.

Last we heard, the EVO Shift 4G was supposed to use a 800MHz, but we’ve all seen what such a CPU can do on the T-Mobile G2, that was overclocked to 1.4GHz. January 2011 is the supposed launch date of the handset, making this Sprint offer a rival for Verizon’s LTE-based announcements.
