Rockstar state that this game does not support cheats. It does however have all the cheats built in from the PC version, but it needs a keyboard to type them in.
On an Android tablet such as the Asus Transformer Prime it has a detachable keyboard dock allowing you to simply type the codes in at will, but with phone its not so easy..
This works on some phone, but I cannot say it will work on all.. Simply hold down the MENU button on your phone for the keyboard to popup allowing you entry of the codes. All codes can be typed either in the pause menu or in-game.
