This is the single most important thing that’s happened to the iPhone alternative market since the jailbreak came out.  David “planetbeing” Wong somehow managed to run Android on an iPhone, dual booting with OpenIBoot. Check out the video below, then check out planetbeing’s post about this, and get the files for what he calls iDroid! It’s not clear yet whether this works on anything but iPhone 2G (as used in the video) – I wouldn’t try this on a 3G or 3GS just yet. But still, this is pretty big!
