Put the iPhone on Any Windows Mobile Phone

While you can argue that Windows Mobile is feature-for-feature and spec-for-spec superior to OS X on the iPhone, Apple's mobile UI is certainly more fun to use. So if you're running WinMo with a hankerin' for rubber band-like scrolling, jiggly icons, screen flicking, SummerBoard themes, and even simulated multi-touch pinching of photos then you're in luck. Flick Software Research is set to release its iSwish interface and iZoom pinch software in beta come "early May."
