With the advent of all these uber cool mobile phone handsets, we want some phone OS love too. Yes, we have the iPhone OS and Android, but Windows Mobile 6 seems to be shrouded by complexity. Head on over the The Inquirer and check out this video of the new, super cool, Windows Phone OS. It looks like their Zune interface, but made all nicey nicey for mobile phones. It was also pretty exciting to hear that it'll be offered as an upgrade on the likes of the HTC Touch Diamond 2. The second surprise is that we should see it just before Christmas 2009.
