GTA Chinatown Wars was originally announced for the iPhone and iPod Touch back in August 2009, and since then, there have been absolutely no reviews, screenshots, hype, or any sign of progress from Rockstar Games. Some thought it might have been cancelled, or at the very least delayed.
While there is still no official announcement from Rockstar, it was released just over an hour ago at midnight tonight (GMT) and is now available to download from the iTunes Store, the 188MB download costing £5.99.
Psy over at iGTA appears to be one of the first to get the game, and you can check out some random screenshots he's taken on iGrandTheftAuto.
UPDATE: The game is now available in the US store priced at .99.
