MonoTouch seems like a great platform for iPhone development, but I'm concerned about deploying it to the Apple Store. Are there any examples of applications built with it that are currently available on iTunes? 

We're starting a new project for the iPhone, and keeping the entire stack in C# would be great, but we don't want to incur the risk of being turned down from the Apple store because of MonoTouch.

I've read about several games that currently use mono (not MonoTouch) for 3D graphics, but couldn't find anything about MonoTouch.
