A few days ago, David Wang posted a video demonstrating how he made Android to run on a first gen iPhone. He dual booted Android and iPhone OS and provided the steps required to achieve the goal.

Today, he has successfully managed to run Android on iPhone 3G. He says that this time the process is slightly risky but promises to put up a guide instructing users on how to run Android on iPhone 3G.

In the meanwhile, you could watch his iPhone 3G running on Android in the video below.
