Windows Phone on an iPhone

Here's something for iPhone users with Windows Phone envy: why not run Windows Phone on your iPhone?

It's actually a browser-based demo of the UI, so it's not exactly "real", but it's a neat idea for giving people something they can try hands-on. (If it works - someone here tried it with an iPod and got the same message I did on a desktop machine - "your device or web browser isn't supported at this time".)
