While the information is slim, the smaller, finer details give us just enough to keep the speculation going. According to an FCC filing, HTC has dropped off a WiMax, CDMA enabled device to the FCC labs for testing. For those of you out there keeping track, these specs fall in line with that of the oft rumored HTC Knight / HTC Shift Evo 4G that's supposed to be heading to Sprint with some Android flavor. Many folks still question the reality of this device, as we noticed in our forums but if nothing else, this FCC finding could mean we are one step closer to seeing it hit store shelves soon.
