On the eve of the T-Mobile G1’s official launch, the source code for the complete Android platform has been released in open source. The code offers an operating system, middleware, key mobile applications and an API for additional applications.

On the Android Open Source Project’s inaugural blog post, Dave Bort says that the fledgling code is “now officially available, for free, as the Android Open Source Project.” Bort goes on to detail all the potential uses for Android beyond the phone, including virtual machines and embedded Linux.

Contributors are invited to add the code-base in an effort to make it the most ubiquitous and thorough platform for mobile phones in the world.
