You might have read about the recently found exploit that allows people who own the game Lumines, to boot homebrew software on their PSP. Of course, that won't affect people who just won't update to that new firmware. Looks like Sony is having a tough time dealing with piracy.

Sony has updated PlayStation Portable firmware to version 3.51 after hackers found a way to bypass security in its most recent update and downgrade firmware.

The virtue of doing that from a hacker's perspective is that older firmware is capable of running homebrew applications and - the bit Sony worries about - pirated games.
