Mod Menu MW2 with Patch Blocker

Hey Guys, is it possible to have a Mod Menu without jailbreaking the Ps3 but having the patch blocker running ? ... i have a Ps3 Slim 320gb with the 4.30 firmware.

i think that it is possible, because if you play with the patch blocker you sometimes get a mod menu ... so u have a mod menu without jailbreaking the ps3. now i thought that it must be possible to have it from the beginning of the game.
has someone a tutorial or a link or knows something about it ?

please answer fast
