Alright folks, pick up your Zune HD player, connect it to your PC and hit the update button. Yes, the most awaited update for the Zune HD has arrived.

The update brings a lot of cool and exciting new features, such as Smart DJ mix, personalized recommendations, Marketplace support for TV, expanded video codec support and so on.

Microsoft today has announced the availability of Facebook app for the Zune HD portable media player. Zune HD 4.3 firmware was released in November last year which added support for running 3D games and apps on the Tegra-powered Zune HD. The first batch of these games and apps finally arrived in late November as a free download via the Zune Marketplace followed by the Twitter app in December 2009.

Its Tuesday September 16th, the day all Zuners have been desperately waiting for since Microsoft’s announcement last week in which it was announced that they are going to release the new firmware and the updated v3 software to enhance our Zune experience. I don’t know about others, but I’m pretty excited to try out some of the newest additions that the Zune Team have in store for all us.
