Computer Science students at the Hamburogh Institute of Technology have successfully ported maemo to the iPhone and HTC Touch Pro. They say they are running it under virtualization technology (similar to VM Ware), so its not really a port, but it does run.

The virtulization app is available for jailbroken iPhones, as well as for any WinMo phone with a large enough resolution. No word on a release date.

Now maybe maemo will become mainstream...
