First time I ever did it, I did it one try.
Start up Cod4, Deny the patch, then press the PS button and move to sign in, but don't do it yet. Wait until you are at Play Online. Select it, Sign in (with a gray background), and press circle after the fade. Then sign in 1-2 more times with the PS button, and you should be in.

Just ignore this; if it happens again turn you PS3 off and on at the back of your system and try again.
