With Sprint's 4G commitment to WiMAX and the support of handset vendors Motorola and Samsung, Nokia wants a piece of the action, too. After all, the world's largest handset manufacturer needs to... well, remain the world's largest. Anyhoo, those Finns have said that it intends to sell "mobile devices using WiMAX Internet technology" as early as 2008. Do we see a heated battle between Nokia and Motorola on the WiMAX handset front next year? Sprint's announcement of a national 4G WiMAX network should be producing fruit by then, we think, so the more manufacturers want to get in on the action (Samsung included), the merrier.
