remember you asked!!
code division multiple access CDMA A form of digital cellular phone service using a broadband digital technology in which the transmitter encodes the signal using a pseudo-random sequence the receiver also knows and can use to decode the received signal. Each different random sequence corresponds to a different communication channel. Also called spread spectrum. Contrast with time division multiple access (TDMA).
Global System for Mobile Communications GSM The pan-European digital cellular system standard (developed by a committee of European telecommunications administrators, operators, and manufacturers), now deployed worldwide at 900 MHz and gaining popularity at 1800 and 1900 MHz. Defines a radio interface based on 8-user time division multiple access (TDMA) with 200-kHz channel spacing and advanced features. Formerly called Groupe Speciale Mobile.
which is better?... its like comparing AM and FM radio... they both do the same thing... but differently

Don't forget, CDMA is the technology of choice of Isreal, Korea, &c., so its international ability is relatively weak.
And don't be fooled that because CDMA is digital technology (wireless techs read digital as TDMA), it's outmoded. CDMA, I've found on par, to be a much more secure form of their digital technology, GSM while still digital is more widely accessible. And plus, with CDMA, you don't hear that crappy techno beat when you put it near a speaker.

how does an individual person find that one technology is "more secure" than another.
