Sony has released a new update for the Playstation Portable in Japan. The new version is 3.70. Europe and US update is just around the corner.

The new firmware update is nothing special, brings custom themes, ability to play movies sequentially, it is possible to assign buttons in remote play, you can now search through scenes while watching a movie and you can now look at photos and listen to music at the same time.

That's all folks, and update works also on the new PSP Slim.
