Also available on the iPod touch, Chinatown Wars will see the full game playable on Apple's devices – although here's hoping the graphics are more like the PSP version than the DS.
Rockstar founder Sam Houser said: "Chinatown Wars is a perfect match for the iPhone and iPod touch. We are very excited to bring this incredibly ambitious version of Liberty City, with this level of detail and immersive gameplay on Apple's new gaming platforms".
If you haven't managed to catch this addition to the GTA family, it follows the story of Huang Lee, a Triad looking for answers (read revenge) after the death of his father.
There's been no mention of date or pricing as yet – but we'll be sure to keep you updated with anything we hear.
