Real Racing, really good!
I just simply had to mention the recent iPhone release of Real Racing by Firemint.
It has to be the best racing game on the iPhone to date. With PSP level graphics what really sets it apart is the AI. Every race you battle with the AI who overtake, block and down right try to ram you off the road!
The only drawback with Real Racing is that being such a great game your battery will get hammered.
