As is the way with most iPhone releases, Rockstar's Grand Theft Auto: Chinatown Wars has been set loose upon the App Store with absolutely zero warning or pre-emptive fanfare.

One moment, we're busy getting on with our weekends, the next, we simply receive word that it's out. Early reports say that the game is as faithful a reproduction of the DS/PSP game as you could expect on Apple's handheld, with even the DS version's touch-screen minigames making the jump to the iPhone/iPod Touch version.

The game controls like most other iPhone ports - there's a fake thumbstick and buttons arrayed on the touch screen - and you can check out a video above to see how it runs.
