Well,that is good.And it's not hard or risky.But you have to copy the whole savegame,and you can change the name in-game. My friend gave me his savegame and he was lvl 1,now he is lvl 6. I tried it,and works.BUT YOU HAVE TO COPY EVERYTHING.
Everything means EVERY SINGLE FILE FROM HIS SAVEGAME FILE.THE ALIAS,CAREER,EVERYTHING... It works on the PB server,because it's not cheating. You just copied it to play easier. You cant play at the same time,at least I think you cant... The CD key is generated by the game. Every game has a different key. I am using one key for both profiles.
You could play in the same server at the same time until the recent PB update, which i heard guid banned people that used the exploit. I haven't tried it myself so i'm not sure if its real or if people are telling porkies.
Its a file called mpdata that you needed to copy and not the saved game as mentioned by someone. To play in the same server, you just change your cdkey back and if you wanted your own name then you typed /name yourname on the console.

1 - Get the mpdata from a level 55 player 2 - Load up CoD4-MW and create new account 3 - Change cdkey to the one he provides 4 - Exit game and put mpdata inside C:\Activision\Call of Duty 4 - Modern Warfare\Players\Profiles\newcharacter\ 5 - Load up game and change cdkey to your own
It probably still works, but its likely the PB is gonna ban you for that exploit.
