The annual update for the Xbox 360 dashboard is here, bringing with it support for Facebook and Twitter integration, and HD streaming through Zune's online marketplace.
To grab the update, just fire up your Xbox and sign into Xbox Live. You should be prompted to apply the update, after which you'll have access to all the new features.
The Facebook and Twitter integration looks pretty solid (and let's face it, Twitter and Facebook are both determined to find a home on every single electronic device you own). Nick at Gizmodo has given the video streaming rave reviews, so that's also a good option, albeit one which might consume your bandwidth at record rates. Overall, if you've got a 360, it's certainly a worthwhile update.
