CES will signal the debut of the Neo FreeRunner phone, maker OpenMoko has announced. Though based on an existing phone called the Neo 1973 (pictured), the FreeRunner is touted as the world's first mainstream phone to run on an open-source software platform, beating out any rivals running Google's Android. It specifically uses GNU Linux, enabling any coder with the skill to write a third-party program.

The FreeRunner also represents a technical upgrade over the 1973, as it has a 500MHz processor, 3D graphics rendering, and an updated assortment of applications. 802.11b/g Wi-Fi enables fast Internet access, and some commands can be triggered through motion sensors.

Two versions of the phone are being developed: one operating on 850MHz-based tri-band frequences, the other working on 900MHz-based tri-band. The former is most important, as it should allow the FreeRunner to operate in North America. The finished product is expected to ship this spring.
