Fans of social networking sites who own an Xbox 360 will be happy to hear the next dashboard update scheduled for Microsoft's hit console will supply music functionality (Last.fm), hyper-tweeting (Twitter), and  "friend" stalking (Facebook). Facebook on Xbox LIVE will not support videos or apps, but you will be able to invite people on FB to your XBL friends list.

Entertainment Manager for Xbox Jennifer Puzio-Brookes modeled the update for a select few in a behind-closed-doors session today. After her performance, Ms. Brookes announced the beta will go live "middle-towards-end of October" -- exciting news for those who were disappointed by the Felicia Day demo.

Like the last public beta, this one will be offered via invite to certain members of the Xbox LIVE community, likely Gold members as before.
