The short answer is that NextG is a version of the 3GSM (the 3rd generation of GSM) running on a non-standard frequency that gives it extra range. The downside is that it requires non-standard handsets (for now).
The long answer is that there are 2 basic mobile technologies at play here
1) "CDMA" and it's evolution to "CDMA2000 1xEV"
2) "GSM" and it's evolution to "3GSM" aka "UMTS" or "W-CDMA"
(there are some other players... Japan has some unique setups etc).
CDMA2000, "CDMA", and 3GSM all use a CDMA based transmission system. 3GSM (including NextG) is well and truly an evolution of GSM, not "CDMA".
.... Naming the mobile system after the technology it uses becomes very confusing when other systems start using the same technology!
ps. using CDMA doesn't make your radio go stutter-crazy when you get a phone call. Both "CDMA" and "3GSM" are much more car-radio friendly
