RIIIGHT RIGGHT buddy. That's why networks around the world mostly use GSM, right? Oh, and how about the fact that some are CONVERTING to GSM and getting rid of outdated CDMA....for example: Upgrade to 3G!!
In his defense, CDMA is actually newer technology than GSM. Also, EVDO is faster than EDGE, GSM is only now surpassing CDMA when it comes to data.
