The latest dashboard which includes the new facebook, lastfm, and twitter applications has been leaked to torrent sites.  The dashboard is certainly an upgrade from the previous version but at this point we recommend waiting it out.  Microsoft has banned Xbox Live access for any gamertags who access this new content that were not invited to the beta.  With the release being a few weeks out to the public it’s probably not wise to download and install this unless you don’t mind being able to get on Live for the next few weeks. Plus what good is Facebook, Twitter, and Lastfm without LIVE access, I’ll tell you it’s pretty useless.  With the only real changes being those features, it is pretty much a waste of time.
