If you have not heard about some groups that are porting the almighty Android OS onto Apple iDevices, then you should really check out the iDroid team. So far really big advances and progress has been made on the iPhone 3G/2G and iPod Touch for firmwares OS 3.1.2, .3.1.3 and iOS 4.0, 4.1 and 4.2.1. With Blackra1n, redsn0w and sn0wbreeze supported jailbreaks.
We need Linux Kernel developers big time for this project as this is the thing that is holding us back. Having people spread out getting started on ports for other iDevices, slows down the updating process. So please visit www.idroidproject.org
We need more development on the kernels for ports to the newer generations of iDevices. If anyone is interested, hop on our IRC #idroid-dev at irc.freenode.net. Any help is greatly appreciated. We even need driver developers as well!
