PLEASE DONT PAY TO PLAY!...
You probably spent enough of your cash on GTA4. Cheat codes are being sold on ebay & its not fair! These codes are free info available on the internet & also official Playstation magazine. These codes work on PAL Playstation 3's. If you sell these codes no doubt you will have to say my guide is unhelpful! If you already paid for them then sorry I didnt get these on sooner! ...
Anyway - to use these codes just pull up Niko's mobile phone & tap in the number...
