Sony has updated the current PSP software manual to be inline with the forthcoming 3.00 system update, due... sometime soon.
The update will provide support for Downloading PLAYSTATION Network titles and then, of course, starting them. You can see in the Starting a PLAYSTATION Network title that you can choose from four button configurations (nice?) and view digital versions of the game's instruction manual (nice!).
Details on PlayStation 3 Remote Play via the PSP are also available for your study, under Operating the PS3 system.
A handful of other cool features, including turning off UMD Auto Start and Timer settings for RSS channels are detailed. Less cool? Certificates (aka inevitable but un-fun DRM) for PlayStation Network titles and needing a PS3 to connect to the PlayStation Store for your PSone downloads.
