The CDMA model presumably has compatibility in more markets than the standard GSM model. According tot he list below, unless you ordered your phone from a Chinese firm, if you have a CDMA model it also supports GSM.
GSM is a European standard and supports the EDGE network. CDMA supports some networks branded as "3G", but YMMV. Both are getting a bit long in the tooth as far as cutting-edge goes (IMO).
