10 is available now. Playstation Network's Eric Lempel describes this as a "big update" which adds Sony's newly announced "SensMe" music mood software.

That's not the big part of the firmware though. For PSP Go users only, you'll be now able to use the system's Bluetooth compatibility to connect to a mobile phone and use it as a wireless hot-spot - essentially gaining you Internet access wherever there is signal. That is a pretty big deal.

Check out "SensMe" after the jump.
