PS3 Firmware Update 1.81 NOW Available

Not a "huge" update by any means, but better than nothing I guess:

The update will fix a few small issues some of you have noticed. Most notably is the RGB Full setting which a few of you wrote in about. In 1.80 we added an option to the XMB under settings allowing you to choose between RGB Full and Limited. Basically if you are connecting your PS3 to your TV using an HDMI cable, and if your TV supports RGB full range, the picture quality may be improved when this option is set to Full. Some of you pointed out that the Full setting would sometimes revert back to Limited and 1.81 will address this issue. Please keep in mind that this setting is only effective when the PS3 is connected to a TV using an HDMI cable.
