PSP games region-free after all, but UMD movies locked

PSPWe've reported before on the fact that some games for the PlayStation Portable do indeed sport a region-coding number, but now that the US games are finally out, we're happy to note that Sony (as promised) did not put a region lock on any of their games. Which means that yes, you can play any Japanese game on that fresh, mint-condition, scratch-free PSP you just picked up (or if you've had a PSP for a few months, there's now a few new American titles you can add to your library). Sony did lock up the UMD movies, so those of you with Japanese PSPs won't get any Spider-Man 2 action.
