Replicant

Build system * root your phone * Backup your current system!!! * Check out the Dream Android repository following that howto: [http://source.android.com/documentation/building-for-dream],but be carefull...DO NOT RUN extract-files.sh...it would put proprietary files in your build,that you can't even redistribute
Android use a custom Makefile based buildsystem * Add the patches that can be find here [http://groups.fsf.org/wiki/Freest_hardware_comparisons/replicant] * Add this patch for sound: {{{
