WiMax has enough bandwidth to be considered 4G, but the tech is closer to WiFi than traditional cellular. And the rebranding you're thinking of is Clear from Clearwire -- WiMax is just the radio standard that they're using. The other 4G will be LTE. WiMax/LTE is akin to HSDPA and EV-DO -- different standards that fall under the 3G umbrella. But if you want to be really pedantic, apparently wimax falls under 3G also (according to wikipeda).
