...on a cdma network?(verizon)? Is it at any way possible at all to have a gsm razr phone work on a cdma network?
And i heard that if you take the lower back off of a cdma razr and put it on the gsm one, it will work. Is that true?

Your talking about changing the main control board of the phone? Why not just use the cdma phone then?

I think that GSM (Global Standard Mobile) uses TDMA which is incompatible with CDMA.
