Microsoft has opened its public beta registration for this year's major Xbox 360 system update.
The firmware refresh will "improve overall performance" and add in the ability to purchase Xbox Marketplace games, DLC and accessories with real world money.
Interested in signing up? You can't apply online this year, unfortunately. You'll have to select the Xbox Beta Program tile on your Xbox 360 dashboard, and enter in your details there.
As usual, you'll need to sign an NDA to be accepted into the progam, which means no spoiling the details online.
