OK. So CDMA is not really old..

There are two Cellular network families.

1. CDMA (voice) – CDMA2000 (basic 2G data) – EVDO (3G Data)… EVDO Rev B (3.5G Data)

2. GSM(voice) – GPRS (basic 2G data) – EDGE (enhanced ‘2.5G’ data) – UMTS (3G data) – HSPA (3.5G Data) – HSPA+ (upcoming 3.75G Data)

The families have different strengths and weaknesses. EVDO has an issue with not supporting Data and Voice at the same time.. But it has much wider range. So you get better coverage with CDMA/EVDO than GSM/HSPA.
