Omg. really? PeXploit is used for installing .pkg files on OFW or Official Firmware by Sony for the Playstation 3. Works on any PS3. ANY! Think of the .pkg files as the games or even the homebrew that you can install on a Jail-broken Console) but these won't work on any OFW console!!) Home-brew doesn't work on OFW. Period. But if you are running 4.66 OFW this is useful for you. you can get free DLC, and mod to some extent. and even get SOME free games! But most are absolute crap. Anyways, you can also not use it to it's full potential if you are running 4.75 Firmware OFW! However, if you are using a CFW console or Custom Firmware console or a Jail-broken one: YOU DON'T NEED IT! AT ALL!
