How do you enter cheat codes on Grand Theft Auto 4?

Answer 1

If you want Niko to dial a number, including cheat codes, press the directional button upwards twice, and you will get the blank screen ready for number input. Use the directional button to go to the numbers you require, pressing "X" to select each number, then select the telephone icon on the left hand side to ring that number.

To enter cheat codes:

Enter cheats during normal gameplay. Find the cheat you want to enter, activate Niko's cell phone as above and put in the numbers using the directional buttons. When the cheat is entered a message will be seen saying "Cheat Activated". Not always a good idea to save the game when cheats are used though.

Answer 2

for PC its the up arrow and up again (this brings up a blank screen) then type each cheat in using the phone number provided with the cheat.

for Xbox 360 its the up keypad then up again (then same above with the cheat)
