Many Windows Phone owners also have Xbox 360s, so we’re bringing you this bit of Xbox 360 news.

The Xbox 360 receives system updates once or twice a year (no carrier blocking either, thank goodness). Before these big updates come around, Microsoft usually runs an open beta to eliminate the kinks and make sure everything’s working right. Sign-up for this year’s open beta has just started.

Some notes about Xbox 360 System Update Preview program:

  • The program is open to US residents only.
  • Thousands of applicants will be selected. Still, signing up early is recommended.
  • Xbox Live Gold members will receive priority, but 'lowly' Silver members can sign up too.

What changes will the update feature? One is a new Xbox 360 disc format is coming. This could be an anti-piracy measure. But the big feature is of course Kinect improvements including the rollout of avatarKinect, which gives your Avatar a new lease on life, hosting shows and making videos--very cool stuff. We would love to see some Windows Phone 7 integration on the dashboard too. It does currently have some ads and videos, but that’s it.

WPCentral’s Daniel Rubino has already completed registration. I tried but received an error after confirming my email address. To throw your hat in, Sign up for the Xbox LIVE Update Preview Program. Good luck!

UPDATE: Good news: participants in the preview will receive a free copy of Halo Reach. Bad news: registration is now closed. Hope you got in, everybody.
