It looks like iOS 4.0 has successfully been cloned to another device, an HTC one in this case, and everything from iOS seems to be there. As iSpazio points out, the porting of iOS to another company’s device seems like a long-shot, so this is most likely the best, most realistic iOS clone ever. As you’ll see in the video below, everything works including folders, quick-app switching, spotlight, and all the keyboards.

You will also notice that the device’s performance is just like an iPhone 3G running iOS 4.0; complete junk. Anyways, this video is still pretty cool as it gives an idea of what iOS would look like another piece of hardware. Hint: Crap.
