News today of new firmware for Sony's PSP going to be available soon. The update will address the following issues:
when playing PSOne games, you'll have the ability to customise your button layout
when deactivating the PS3 Remote Play function, you'll be able to leave your PS3 running or switch it off remotely. This last one is useful if you want to continue a download without switching off the PS3 when you disconnect the remote session.
