"Update: Comments for this story confirm that using some of these cheats will not allow you to unlock certain achievements.Having a tough time getting your revenge on in Liberty City? Thankfully Game Trailers user GhettoChild discovered the cheat codes in Grand Theft Auto IV for everything from restoring health to spawning an Annihilator helicopter. Using the in-game cell phone you dial the phone numbers to activate the code. While we haven't been able to confirm it, we assume using any cheats will no longer allow you to unlock any achievements and based on Rockstar's past with using codes, you may be unable to watch the final cinematic in the game.Don't say we didn't warn you. Codes after the jump.[Thanks, Chris]How to use the cheats: Press up on your D-Pad to display your cell phone, and then press up again to access the keypad. Enter the codes and call the number. If done correctly, it should say \"Cheat activated\" in the top left hand corner.482-555-0100 Restore health362-555-0100 Restore armor486-555-0100 Get a selection of weapons486-555-0150 Get a different selection of weapons267-555-0100 Remove wanted level267-555-0150 Raise wanted level468-555-0100 Change weather359-555-0100 Spawn an Annihilator938-555-0100 Spawn a Jetmax625-555-0100 Spawn an NRG-900625-555-0150 Spawn a Sanchez227-555-0100 Spawn an FIB Buffalo227-555-0175 Spawn a Comet227-555-0147 Spawn a Turismo227-555-0142 Spawn a Cognoscenti227-555-0168 Spawn a SuperGT948-555-0100 Song informationThese cheat codes work for both the Xbox 360 and PS3."^^<http://www.w3.org/2001/XMLSchema#string>
