Some folks might be interested in the GTA02-core project:
http://wiki.openmoko.org/wiki/Gta02-core
From the Wiki:
"gta02-core is an experimental project to explore community involvement in the development of hardware for potential future open phones. The aim is to develop an incremental improvement on existing GTA02 designs, while replicating the necessary CAD files in a open format."
GTA02 being the Openmoko FreeRunner phone
Yes, that is very promising! And the good side is that there is some active support from Openmoko (e.g. providing some internal documents under GPL or Creative Commons).
Someone has already started to redraw the schematics in KiCad (an open source Electronis-CAD tool).

BTW: there is already an Openmoko subforum on OESF
