(adsbygoogle = window.adsbygoogle || []).push({}); i no in cod4 u could do coloured classes with USB, anyway you can do that with MW2?

Look in the modified lobbys section for a free lobby most patches will have a colored class menu.
If you have a 3.55 ps3 and a up to date ps3 you can put the patch on yourself.

Most likely look for a lobby you may have to give your account info to the hacker.

You can only mod your split screen classes with a usb.
