A number of manufacturers produce modular components suitable for embedded systems. Some of these components are suitable for a hobbyist to put together a modular phone. This page is intended as a starting-point for building an OpenMoko compatible phone.
The major problem with this approach is that the resultant phone tends to be larger than a normal phone.
This is because though they may be designed to be compact, internal connectors add lots of volume compared to a PCB, where everything can be in one unit.
