Actually many believe that TDMA will end up having to "switch" sooner or later. They're happy at the moment because for a time it appeared that the ITU (Intl Telecomm Union) would exclude them altogether from the standard. ATT is the TDMA "gorilla". Their economic rational is not exactly the same as other purely wireless carriers like VOD/ATI. They can run ATT wireless as a loss leader to capture one stop shopping biz even if the wireless pricing pressure gets very tough and they're losing money because of their inefficient system. In any event, TDMA and GSM are cousins, there will soon be a GSM/TDMA phone so roaming on ATT in Europe will be a reality. TDMA is supposed to not be good for data however so we'll see have to see how this plays out.

Mike: Re probable 3rd gen phone configuration, your understanding is wrong. Sorry about that. Almost but not quite. The least likely is a phone with all three modes. TDMA will go its own way probably with some combination with GSM where possible and practical. No one is likely to bother with a TDMA combination with CDMA - no point in that. There will be CDMA only. GSM only. A combination of both with Globalstar satellite. CDMAOne (IS-95) of various upgrades combined with CDMA2000. CDMA and old fashioned cellular. And on and on. AT&T will push a combination TDDA and GSM phone (a world phone) so called. :-) The dying technologiies combined. What fun. But AT&T's huge marketing clout make this a force to be contended with in the US - but in the US only. I have only scratched the surface here, and as you well know, I ain't a tech wiz. Suggest you raise this on the SI Q thread where such tech wiz's abound. Best personal regards. Chaz too PS But all this is guessing at this point. The "standards" are in process of real world discussion in London right now with Vodaphone/Airtouch taking the lead and the service providers pushing for convergence. Phone configuration will depend on outcome. But again, 3 mode combination least likely phone box.
