ATM cash glitchFind an ATM then block off traffic in the road leading to it so cars cannot pass. Then wait for someone to use the ATM, kill them then take the money they drop. It's essential at this point that you have done a good job at blocking the roads so the ambulance can not take away the corpse.
With that said... Run a bit away from your victim and go back again and the same money should be available to pick up again... If anyone is using the ATM when you go back you can kill them too and each time you return their cash will have respawned too.
Repair car engineBroken down? Car on fire? Try calling 911 using your cellphone in the game, the emergency services may come and your engine will be fine again.

Faustin's MissionsAfter you meet Faustin, complete ALL 100% of his missions, before attempting Dimitri's missions, as Dimitri has you kill off his best buddy Faustin. Therefore making him unable to give you his final lot of missions and you'll be unable to get 100% completion of the game overall.
Phone cheatsIn GTA IV cheats are activated via using the mobile phone. Try entering any of the following codes after Roman has given you his old mobile phone. This happens pretty early in the game so you don't have to wait long before you can enter the cheat codes. Once you have the phone you can enter them as often as you like.
Okay, first get out your mobile phone and press x to raise the phone higher and reveal the complete keypad then use your controller to select the set of numbers according to which cheat you want to use, after you have entered the code the cursor moves to the dial button, just press x again and if successful you will see a message 'Cheat Activated' on the screen.
It's still early days for these cheat codes, so we advise you not to save your game after you have enabled a cheat code.
