Microsoft has, just like earlier in the year, offered its users the chance to take a look at the forthcoming dashboard upgrade a little early in the hope of getting rid of any bugs that testers might not have spotted.
The next version of the dashboard will have, as previously reported, integration with Twitter, Facebook and Last.fm, as well as the Zune video marketplace and its associated instant-on 1080p high definition streaming. Here in the UK, we'll also be getting the Sky Player. For most of that lot, though, you'll need an Xbox Gold subscription.
If you'd like to sign up, you'll need to be in an Xbox LIVE region, know your console ID, ISP, make and model of your TV and router, and how you connect your Xbox to your network and your TV. Even then, there's no guarantee that you'll get in - Microsoft is being picky about who gets early access.
If you still feel like trying your chances, then head over to the Xbox Live Update Preview and fill in all your details. Good luck!
