Just curious how did you get the CDMA part to work? Did you simply insert the SIM card or did you have to register via Verizon (or the carrier's) website (I'm assuming you mean Verizon when you say CDMA)?
I know for CDMA you used to have to register the phone via Verizon website in order to get it to work, since there is no SIM card for CDMA registering your phone was always necessary.
