To pirate a game for PC, Xbox 360, or Wii is (unfortunetly) very common. And now people succeeded in hacking the Playstation 3. On the 27th Chaos Communition Congress the hacker group "fail0verflow" did their presentation "PS3 Epic Fail" about how to do it, and it's on youtube, "Console Hacking 2010", 44 minutes long. You can install now without any 3rd party programs any unauthorized programs, like Linux, Homebrew, and of course pirated games. Which is strictly illegal.
This access for everything on your PS3, what fail0verflow managed to do, means: times are coming for the Playstation Network in which they fight against cheater and hacker in online games because you can install now cheat software of course, too.
