Kernel source and other OSS portions ready for third-party developers
You'll find the source files for the kernel as well as other essential and GPL portions of the system, and a nice set of instructions about how to get it all to compile. Most of us won't have a need for these, but I have a feeling that the best budget phone on the planet will see some serious development, simply because it is so accessible.
If you are the type who wants to dive in and have a go with these, grab them right here.
