You’ve got to pat Sony on the back for giving it the good, old college try. After the Lumines hack debacle, Sony is trying to fight back with a 3.51 update that has been added today over at their Japanese site which would close up holes in the PSP’s security . Other than just the security fix, there isn’t much else you would need the update for. There is no added functionality included in the update and none of the currently released games will require it. But if you just love updates, and hate hacks, you’re more than welcome to go pick it up.
