It is really too bad, I have a GTA02 OpenMoko, also a GDC phone and it was a substantial device with a real FOSS OS.
You had to tickey tack everything out on a microscopic keyboard from CLI using a stylus but it was a real computer in your pocket. I still had my everyday use Zaurus SL-5500 at the time though which IR tethered to my Nokia 6100 to get online, the Z was a Linux w/hardware keyboard pocket PDA.
