If you don’t know by now a jailbroke iPhone means you have broken out of the constraints of the factory setting, and are able to get apps that are not offered in the app store, and the recently released Bootlace 2.1 application for jailbroken iPhones let’s you install android(No Computer Necessary), but Unfortunately, it only works with the iPhone 2G and 3G at the moment, but it will let you install Android 2.2 (a.k.a. Froyo) directly on the device without the need for a computer. Ironically enough most android phones are only running 2.1!
