Yes there is a Call of Duty 4 for the PS3, depending on where you live, go head on down to your local game store. (e.g. Thunder Bay - EB Games) You'll probably be able to find a cheap used/new copy of Call of Duty 4 for your PS3.
You have to hack Call of duty 4, but don't. Don't cheat by hacking into the system. I know how, but I would never do it.
