It is recommended that PSP Blender members do not update their firmware to 3.10 for the time being.
Sony released their PlayStation Portable firmware update, 3.10 and now makes demos even easier to check out.

Sony announced the release of the Sony PSP firmware 3.10. It includes Conserve Memory to optimize your Internet browser to see more data while using less memory. Also included with this firmware update is Dynamic Normalizer in the sound settings allowing automatic volume adjustment settings for playback of music and other audio sources with variable output levels.

Sony is also making it easier to check out their demos. Demos are downloadable at the official Sony PSP site as well as at the PlayStation site.

Some of the demos that can be downloaded are Killzone: Liberation which is a third-person shooter putting players into 16 intense missions to rescue hostages from the evil Helghast. Other demos include Syphon Filter: Dark Mirror and SOCOM: U.S. Navy SEALs Fireteam Bravo 2, both of which are set for release in the next few weeks.
