Currently there is no such version planned.
The reason is simple:
Openmoko is about free phones.
We are currently not aware of any carrier using CDMA and supplying R-UIM (smardcards, similar to SIM cards in GSM networks).
Every phone needs to be provisioned by the carrier itself.
Most CDMA phones do not even have a R-UIM slot it seems.
Thus a CDMA Version is currently not feasible.
This page is to suggest the possibility of a CDMA version of the OpenMoko and see if there would be any interest in accomplishing this:
