Just like Microsoft had promised, sign-ups are now available for the new Xbox 360 Dashboard Update Preview! This new update includes the integration of social network services such as Twitter, Last.FM, and Facebook. Now you will be able to connect with your friends on Facebook, directly from your console. Like to Tweet? The new update will also allow you to read, reply, and post Tweets to Twitter through Xbox LIVE.

Of course, only a selected few will be chosen to beta test the new Xbox 360 Update Preview, but don't be too disappointed. According to Major Nelson, Microsoft will be looking for thousands of people to test the update! Any owner of an Xbox 360 is valid to join, but you must be a Gold Member to have access to all of the new features.

If you are interested in signing up, head on over to the Official Xbox Website where you can find more details and information about this opportunity. Hurry up and apply, there is a limited amount of applications that will be accepted.
