The iDroid Project has released a preview build of Android Gingerbread for iDevices.
This is a preview release of Android Gingerbread (2.3.1) for Apple devices, I am busy with other projects for a few weeks and the other 3 active developers are working on porting openiboot to the iPhone 4, iPad and 3GS, so I thought I'd put a test build out for everyone to have a mess around with, please read this post fully before trying it.
The release is for iPhone 2G, iPhone 3G & iPod Touch 1G and is ONLY available as a binary package. It is not available through Bootlace at this time.
