I think there is some confusion here. GSM's last technology jump was EDGE. GSM is a TDMA network. UMTS/HSDPA/HSPA and HSPA+ are all CDMA air interfaces. GSM annot mix voice and data at the same time, it takes a wideband (5MHZ channel) CDMA product to do it. Versed is mistaken, virtually EVERY carrier went to CDMA in one form or another. GSM has been described as the best piston engine fighter in the jet age.
CDMA has rev B and rev C which were cancelled by U.S. CDMA carriers for WIMAX/LTE
