So then, I guess this is the game plan?
1) Obtain GSM TA backup (and IMEI from the phone it was backup from) and TA backup from CMDA device.
2) Flash TA backup using Omnius.
3) Obtain unlock code from Ericsson.
4) Attempt unlock
5) Assuming successful, reflash CDMA TA and you will be left with an unlocked phone?
6) Assuming unsuccessful, reflash CDMA TA and pray it gets you back?
