GTA 4 Cheats and Codes for Xbox 360 and PS3

I know, I know, Grand Theft Auto 5 is the hot item right now. But in revealing last week's top Xbox LIVE Activity, I noticed an increase in the number of people playing Grand Theft Auto 4. I'm not entirely sure if there's a correlation between the two (though I believe there just might be), I figured why not offer some cheats and codes to those of you enjoying GTA 5's predecessor.

Below are the list of cheat codes available in Grand Theft Auto 4. To enter a code, press Up to display Niko's cell phone while playing the game. Press Up again to access the keypad and then enter one of the following codes to activate that corresponding cheat function.

Once a code has been entered correctly, a new "Cheats" menu option will be available on your phone, below "Options", where you can access the cheats without having to enter the phone number again.

Dial "3625550100" on the cell phone. If you enter this code while in a vehicle, it will also repair it.
