Ex Reverse engineer (and current iPhone Developer) Nope, you can tell. Especially if you have the tool itself on your desk when you try to develop a test (as Apple will surely be buyers of). If it doesn't look like Objective C, C++ or C in its call parameters, flow, etc, they'll "know" well enough to hold you up in their queue process until you "send screenshots of the source" The boilerplate code technique (where C code is generated) can even be detected (although has more false positives). The Adobe sourced Flash binaries are supposedly trivial to tell, and I'd expect MonoTouch etc to also have that issue.
