Well, the fact is that I have written Java, C, and C++ code that is translated into C# applications threw an automated process. So, even given that you STILL can write native apps using a C compiler directly, you can also create applications in any language that can be translated binarly in IL or C#. This is exactly what the new iPhone terms attempt to make illegal, as there were a number of applictions that converted Flash, .NET framework code, etc. into binary code that could execute on the iPhone. Though exactly how they can prove which language was used to create binary code is fuzzy, it is def the area of lawyers and unfounded lawsuits.
