Hackers Install Android 2.2.1 on iPhone 2G/3G
A group of hackers managed to develop a way to install Android 2.2.1 (Froyo) on iPhone 2G and 3G without the need to use a computer as an intermediary.
DownloadSquad team found the program that allows running Bootlace in Apple smart phones that have jailbreak done by tools PwnageTool, Redsn0w and Blackra1n, thus creating a kind of dual boot on the set. Redmond Pie offers detailed instructions on how to make this change of operating system on the iPhone. But it’s always good to remember that both perform a jailbreak and install Bootlace end up with the guarantees of your appliance.
Basically the user needs to do the jailbreak on the iPhone and install an application called Bootlace 2.1. And then download the app OpeniBoot, which allows you to install another program called iDroid. Users who have tried to install the program reported that some functions of audio and WiFi did not work on Android, and some people reported that they were unable to complete the installation of the program. It is up to each user to discern what is best for your device.
