Listen. This should be the final post... I'll explain everything you need to know about MW2 patches and PS3 jailbreaking.
1. There is no jailbreak/CFW publicly released for 3.56+ FW, and there may never be.
2. If you want to host MW2 modded lobbies (With menu) You must have a PS3 on 3.73 and another PS3 on 3.55 CFW, install Comgenie's Awesome File Manager, copy the patch_mp.ff to a USB stick, copy it to the BLUS30377 folder (US only) on CAFM, and data transfer the modified patch over.
3. If you want to host MW2 infection lobbies (Checkerboard map) You must have a friend infect you, then you just go sit in a pre-game lobby while others join you.
4. The best modded patch out (in my opinion) is JonoEfthy's v9 patch,
You must login or register to view this content. It's sleek, has a nice layout, and has MANY mods.
5. Anyone saying they can infect you with a menu or give you a 3.56+ FW jailbreak is LYING.
6. ???
7. Profit.
PS: Many people in the Modern Warfare 2 Exploits and Hacks section are trolls. Most people who troll here, however, are patch makers and are very knowledgeable when it comes to stuff about modding this game.
