The PlayStation 3 just got updated, bringing the machine's firmware to v3.55. Sony say "this is a minor update that adds a security patch". What ever could they mean?
They're surely referring to a recent upsurge in "jailbreaks" for the console. A few months ago, devices went on sale that allowed the copying of PlayStation 3 games. While Sony was quick to block these devices' access to the console, recent improvements made to the jailbreak tools have let them back in the game.
