Apple Blocks cross compiled app with iPhone SDK 4

For my apps, I have only used Objective-C and XCode for development. Friends and fellow developers have send me links for Cross-Compilers that allow you to write code in everything from C# to Adobe Flash. Well it seems Apple has a "Block for that"

In this article on Daring Fireball John Gruber points out the section 3.3.1 in the new version of the iPhone Developer Program License Agreement.

So it would seem that your either playing with the tools you given or your no longer allowed to play in the game.
