Our buddies over at Phonescoop spotted a handset running a copy of the as-of-yet unreleased Windows Mobile 6.5.3 floating around at CES, and were nice enough to snap some footage for everyone not living in the Las Vegas Convention Center this week. They run through just about everything 6.5.3 has to offer, from the new finger-friendly UI to the brand new, seemingly much improved onscreen keyboard; if Windows Mobile is your thing, be sure to check it out.
