Microsoft's interim Windows Mobile update could have significant updates designed explicitly for touch, a pair of leaks show. A Microsoft representative seeking anonymity has claimed that previous shots of "6.5.1" are accurate but that it's not necessarily a straight patch. Instead, the larger, bottom-only buttons are meant to provide an alternative interface for capacitive touchscreens; the existing top-and-bottom split makes those items too small to hit with a finger, the employee told mopocket.
