As far as im concerned the cdma has two processors arm11 and arm9, one for the radio, one for the system. It is impossible (or not yet done) to overclock the main possessor without messing up the other. Maybe in the future, but not now.
ps: this has been discussed many times over at xda
pps:to avoid confusion, htc performance (an overcklocking program) does not affect the speed of the cdma touch, it just does not say that it didnt making it seem like it did.
