The PS3's newest firmware upgrade, 3.0, is now officially going out to all the consoles in the land.
Go to "System Update" in the XMB to get the update, which replaces the Information Board with an icon-based system called "What's New," plus premium themes, trophy displays, and a status indicator at the top that shows things like number of friends online and messages. Check it out and let us know of anything else you find hidden in the update.
