In typically iPhone fashion, Rockstar Games released the iDevice version of GTA: Chinatown Wars on Apple's App Store with no warning of its arrival.

Priced at only £5.99 - much cheaper than you'll be able pick up the open-world action game on DS or PSP - Chinatown Wars appears to be an absolute steal. The PSP and DS versions ranked amongst the best games of 2009 and you can expect a review of the iDevice version soon.
