OpenMoko is an attempt to create the world's first completely open mobile phone software stack.
We believe in standardization bottom-up (defined and implemented by the community), instead of top-down (defined by a consortium).
For a more thorough introduction see this announcement
OpenMoko is supposed to run on all kinds of Linux-capable mobile phones. The first fully supported OpenMoko phone is the FIC Neo1973.
This initative has been initiated by FIC Inc. and OpenMoko, Inc.
