"It is recognized that [4G], while undefined, may also be applied to the forerunners of these technologies, LTE and WiMax, and to other evolved 3G technologies providing a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed."

It appears that tablets will be a major part of the US 4G war. Like its rivals, T-Mobile has promised to release 4G tablets next year. Here's the official statement:
