Despite this not being a video showing the iPhone 3G running Honeycomb (which would have been much more impressive). The hack below does allow you to dual boot either iOS or Android 2.3 Gingerbread all thanks to the OpeniBoot software, so it should also work on an iPhone 2G or a first generation iPod touch (up to iOS 4.1). The video is a bit jerky, but it's proof that Gingerbread can be dual-booted.

OpeniBoot is an open source software based on iBoot that allows jailbreakers to insert their own code such as Linux kernel into iPhone and iPod touch.
