With UMB officially out of the picture, carriers effectively now have only two options when choosing the faithful path to the fourth generation: LTE and WiMAX. There's no question that WiMAX is quietly gaining traction in pockets around the world, but LTE still commands the lion's share of attention -- and it's especially interesting every time a current CDMA network chooses the GSMA-backed tech. Confirming earlier rumors, Japan's KDDI is the latest to swing that way, hooking up with Hitachi and Nortel to deliver an LTE overlay that's interoperable with its current EV-DO infrastructure. Odds are they'll be offering 20-megapixel cameraphones with 1080p displays by then, too.
