psn gameshare activation

hi
ok so i gameshared with this dude on psn and i got cod4 but after the gameshare and the next morning he told me that he doesnt like my game and he is going to deactivate my ps3 on his account so i turned my ps3 wifi off and disapled internet connection but one of my friend told me that some games dont need console activation because i want to play it online and i cant because if i go online the game will stop working

so if its possible can i get a list of ps3 games that dont need console activation and i would like to know if cod4 does by the way i gave him 007 goldeneye reloaded

thanks
