Is your PSP hackable? Know before buying
The guys at PSPhacks have released a nice article explaining how you can get a PSP that is hackable, or at least downgradable.
Before you buy a PSP for that special gamer this Holiday season, you have to ask yourself one thing: do they homebrew?

You can determine the firmware version by checking for a letter code above the UPC on the bottom of the box.
