Cheats in GTA IV
I prefer completing the game without cheats; So I never save the game when they are enabled. However, I do sometimes use them if I need to get out some aggression real quick before I go to church or whatever.
(The cheats get stored in your phone so you can call them up quickly. You can just save a game with cheats and a game without. Just to be safe, turn "autosave" OFF when you are playing on the cheat game.
