Those of you who woke up extra early this morning to get in precious alone time with your Xbox 360 (we understand – we do it all the time) may have been tricked when a mandatory system update greeted you in place of the dashboard. Alas, the much ballyhoo'd Facebook/Twitter/ update has not yet arrived, as Microsoft's Major Nelson points out on his site.

Instead, the update brings with it support for the now five-year-old WPA2 security protocol. With that new and improved 802.11n wireless adapter hitting retailers next month, and with WPA2 certification being mandatory for all new Wi-Fi devices as of March 2006, Microsoft seems to be rolling out that addition in software. That's good news for those of you with a four-year-old Xbox 360 Wireless Adapter!
