| CDMA Doesn't have this problem because of it's spread spectrum technology. It's possible to crack CDMA though highly unlikely. And I actually could care less if someone want's to monitor my call's because the only thing im saying in my conversations is, I'm sorry your cutting out, I have AT&T and I can't hear you!

| You really believe CDMA is secure? LOL. They're listening in on your CDMA calls just as easy as GSM, trust me. |

With CDMA, many calls share the same frequency at the same time, and without knowing the proper spreading key, you can't even identify which parts of all the junk on a given frequency belong to which conversation. It's not that you have to decrypt the data stream; without the spreading key, you can't even find it.
CDMA was originally developed for the US defense department in the 1940's to provide a communication protocol that was inherently difficult to eavesdrop or jam.
As for listening in, it is a heck of a lot easier for security agencies to just tap the number in the cell provider's network after waving a piece of paper labeled "national security" at the provider. |

| cghh, precisely. Which really makes the whole discussion pointless, at least vis-a-vi government or law enforcement. For corporate espionage and the like, however, it is a valid point. |
