does this actually fix anything?
Increases security of the PS3 console, and increases compatibility with PS1 games.
Oh, wait, that's what the PSP upgrades do.
Question for all of you who upgraded - can you check the store and see if the Folklore demo is still up to download? If so, I'll upgrade (as you have to be fully patched to hit the store). If not, I'll wait for a good reason to patch.
