An Xbox 360 firmware update went live overnight/early this morning. Although it lays the foundation for the 360′s Facebook and Twitter capabilities, no new features are included in this download.
Major Nelson confirmed the new firmware in a late-night post; also, for any of our friends who were up late and gaming and found the system update spit back a router error when connecting to Xbox Live, that has been totally resolved, tweets the Major.
