The thing I'm most excited about is the fact there are now many developers working on several different things... a pretty big change from when I was hacking on the source tree virtually alone. There are developers actively working on the first generation iPod port, the iPhone 3G port, and a second-generation iPod touch port and things are moving much more quickly than I've anticipated. With so many helping hands, I'm sure that we can get these ports to production quality.
To coordinate our efforts, I've setup a series of git repositories on GitHub. You can clone the Android tree using Google's repo tool thus:
repo init -u git://github.com/planetbeing/platform_manifest.git -b android-sdk-1.6_r2-iphone
This command populates the majority of the tree from the main Android kernel.org repositories, with any changed project from my tree.
git://github.com/planetbeing/kernel_common.git branch android-2.6.32-iphoneis our kernel tree. It is included in the main repo checkout as well.
git://github.com/planetbeing/iphonelinux.gitas always is our openiboot/bootloader tree. New hardware support will be trialled there and then ported into the Linux kernel.
A fellow with the nickname of "konaya" on IRC has volunteered to administer a website for us at http://www.idroidproject.org. We can use the wiki to document iPhone Linux/iDroid and the forums to provide help to newcomers. We also have a developer mailing list (please ask in IRC if you wish to get added to that).
