Just so you guys know, no more hacking is aloud, so it's over. And let me tell you how and proof. First, you put the hacks in, then you overwrite, then you start COD4, go to Multiplayer, Play online...then what...downloading game settings?... Durring this time period, the patch disables all hacks from the time you loaded them. It will revert them to the point where you didn't overwrite. No, unplugging your Ethernet Cable won't work.
PROOF? Put in any code, random, anything, in GRAD0MP or GRAD0CM. Go to Play Online, after it downloads game settings quit the game and transfer the save on the PS3 over to the Flashy Drivey. (lol) Next, open the junk in NotePad and take a look. ERASED!!
ZOMG WHAT COULD HAVE HAPPENED!!!???
