TO my knowledge, there is no "All Area" cheat. There are cheat codes to summon cars, gun, ammo, life, etc... but travel must always be done manually or in a taxi. As there are no "locked" areas within the game, I am unsure what exactly an "All Area" cheat code would do. However, you can check the link below to view a complete list of cheat codes that are verified to work on GTA4:

Hello shaquille. In order to reset your cheat codes you must enter the same code you used to activate the cheat to deactivate it. However this does not work will all cheat codes. Hope this was helpful.

Depending on the patch version, cheats may have been disabled. If they previously worked with this install, then something was changed in order to stop the functionality.
