This is just a friendly reminder (as if the new clothes and accessories for your avatars weren't clue enough) that today is the day for the big Xbox 360 system update which brings with it all kinds of new integration. If you got in on the limited preview, than nothing you'll be seeing today will be new to you. But for the rest of us, the long awaited (or at least long promised) integration with several social networks, as well as some updated integration of existing features are now available.

Some of the highlights include the ability to update your Netflix queue right from your dashboard, as well as inviting your friends' avatars to Netflix movie parties. Also going live today is the Games on Demand section of XBL, where you can purchase digital copies of full 360 game releases (provided you have the HDD space). There's also a section that allows you to view download and print the manuals for the games you buy through this service.

A full list of the additions to the update can be found at Xbox.com. Has anyone else downloaded this yet?
