Sony has released updated PSP firmware 4.00, which adds Google search feature, allowing users to use the Google search engine straight from the XMB (XrossMediaBar), aiming to replicate the Google Internet search experience.

Another new feature is the ability to speed up and slow down playback of video files that stored on your Memory Stick PRO Duo.
