Korean cell carrier KT today upended the tablet market in its home country by launching its own model both ahead of Apple and Samsung. The Identity Tab is a seven-inch Android 2.2 tablet, much like the Galaxy Tab, but is aimed distinctly at Koreans signing on to its service. It comes with a DMB TV tuner for over-the-air digital video in the country and, when attached to KT, arrives with a WiBro (WiMAX) card for 4G, albeit likely for sharing data from a nearby computer.
