A new Android device may be hitting Sprint soon. The alleged HTC Knight. The device features a similar design to the EVO 4G, though if you compare them side-by-side, you’ll notice several differences, the most obvious being the different earpiece and additional space below the buttons.
This just might be a CDMA version of the Desire Z, since some literature associated with the device implies that it has a sliding screen (and a slide-out keyboard of course). Hopefully we will know more soon.
