(adsbygoogle = window.adsbygoogle || []).push({}); Basically, here are the steps i used to bypass the patch and it worked on a 2nd account on a new ps3.
Works for Ethernet Users for sure with NAT Type 1 & 2
[[EDIT: I said it Works for Ethernet USers For Sure. That means it COULD work for wireless internet. Just to clear things up.]]
1. Set your date and time to 7/7/09
2. Have 60 friends or higher
3. Copy Save Game data to a usb device
4. Delete the COD4 patch
5. go to your computer/laptop and insert your desired hacks
6. overwrite the gamesave frum your usb device
7. Go to call of duty and play
8. When it asks for the update, simply click O
9. Now press the PS Button & turn off Auto-Sign in
10. now sign in thru the Cross Media Bar & when it asks for the update, keep pressing O fast and sign in and out like that until you get through to where you see Account Management
11. You should be around Halfway thru the cinematics before you login or though the whole Cinematics for some people

The reason for 60 friends is because it sends a message through the server to you friends saying you are offline when you are really online. BUT.....if you don't have 60 friends, what you can do is:
Join a Ground War game that hasnt started yet, wait until 1second, leave, and add everyone that was in that game through your Players Met Section.

Hope I was a help to some people.

-PS If it worked for me, it should work for everyone because I havent bypassed the patch in ages.

[EDIT: You can do this thru the Multiplayer Section if the Cinematics way didnt work. Has to be right after it

Confirmed working on mediocre wireless connection

Can I just ask a quick question: What is XMB?

Cross Media Bar

when you press the PS button, It goes to XMB.

If this works I will thank and nominate

i will try it :d

One question though,

10. now sign in thru the XMB & when it asks for the update, keep pressing O fast

Does that mean don't try and sign in again or what?

so wats the patch look like?...is it the original code which you have to overwrite with the hack code?...not too familar with things..

What do you mean what does the patch look like?
You're just trying to bypass it so you can use you edited gamesave file
