Rockstar Games just announced that Grand Theft Auto: Chinatown Wars will be released for iPhone and iPod touch later this year. No screenshots have been released, but the game is being developed by Rockstar Leeds and will be available in the fall.
The game was released for Nintendo DS earlier this year and is currently the console's highest rated game according to Metacritic. A PSP version will arrive at around the same time as the iPhone version.
When released on the App Store, the game will face some competition similar titles like Payback, Gangstar: West Coast Hustle and Car Jack Streets. GTAGaming covered Car Jack Streets a few months ago when it was released by Tag Games, a company founded in the same city as DMA Design/Rockstar North.

This is very interesting - the fastest selling console game on iPhone. And in my opinion it's the best version since Vice City. Can't wait!
