Yes after you enter one go to the bottom of the phone menu.
To enter cheats, dial the number using Niko's Cell Phone...To access more cheats, open the phone, go to the menu and scroll to cheats :)
nope

No. Unless you Start a new Game.
Dude, just google "GTA IV cheats" and enter the phone number into your phone in the game(press "up" twice on the D-pad).
You just directly type cheats. Type the cheats while game is running. You can also escape out and then type cheats on menu and resume game.
Most cheats in any of the Grand Theft Auto games can't be turned off. You will have to start a new save.
no is doesnt ruin your game. but some cheats block soms achievements
the cheats are different
Just type it in once and go to your cell phone, the last option is cheats, the last cheat should be in there.
you enter phone but klick on the key thing on your controller twice to enter cheats(only on single player)You would enter them into your phone. Once entered, you can then re use them by going down to the Cheats Section of your Phone and selecting the desired Cheat.
