Just like GTA IV, The Lost and Damned, and The Ballad of Gay Tony, cheats are activated through your in-game cell phone. After entering a cheat code, it will be stored in the phone and accessible from a "Cheats" menu at the bottom.
Unlike the other video games mentioned above, entering cheat codes will not block achievements/trophies permanently. You can also delete the cheat codes off your phone.
These are the list of cheat codes:
