The summer dashboard update for the Xbox 360 is now available to all Xbox Live members.
Major Nelson
tells us, "Over the next few hours - or the next time you sign into Xbox LIVE after that - you’ll receive a prompt to accept this mandatory update." SPOnG's turned on the 360 sat under our awesome telly and can confirm the update is indeed good to go.
A couple of points the Major wants you to bear in mind:
"- While you can browse and purchase Avatar items and full Xbox 360 games in the console with this update, the ability to add these items your Xbox 360 download queue from Xbox.com will be available this Thursday.
- Xbox LIVE integration with Twitter, Facebook and Last.FM will be available later this year.
- Zune Video Marketplace will also ship later this fall when it will replace the current Video Marketplace."
