Cheats in GTA IV

Cheats in GTA IV are activated by typing the cheat phone number into your mobile phone. After this has been done once, the cheat will be stored in your phone, and accessible from the "Cheats" menu there.

Be warned that entering some of these cheats in the game will disable certain achievements in the 360 version, so do so at your own risk. Accessing Secrets is different than cheats, and will not affect the status of your gameplay. There is no way to unblock the achievments unless you re-load your game and haven't saved after the cheat has been activated.

• Calling any other random number you find in the game from stores, posters, ect. will allow you to prank call that number.
• Note that out-running cops who try to stop you skipping islands when you are in a spawned Jetmax will NOT give you the Walk Free achievment, but you can get it later on in the same save file after you are killed.
• If you have completed all 30 of Stevie's Car theft missions, you can pawn any car you want for money like you did in his missions. If you spawn a car, you can make as much money as you want. The cars are worth about 1/3rd of what they were in his missions but you can do it over and over and over again.

Keep in mind that this table is presuming that the car is just spawned and has not taken any damage.

Vehicle	Price
Cognoscenti	$8,000
Comet	$5,000
Super GT	$10,500
NRG 900	$1,500
Sanchez	$700
Turismo	$10,500

The FIB Buffalo is the only unsellable spawn car. The Annihilator cannot fit in Stevie's garage and it is unlikely the Jetmax will either but it has not been proven.
