q_long, << So in essence you agree the CDMAone migration path is forward and backward compatible (voice) and a GSM handset will not work on a WCDMA network. Right? >> No. That is not what I said. I think that it is time that you started to do your own homework. Please reread my post and go determine for yourself what a MSM6200 chipset does for a GSM/3GSM handset. - Eric -

>>"Like an handset IS95 works on 1XEVDO network" Now there's a good trivia question. I don't believe it does. You sometimes hear people refer to DO as "data-only" instead of data-optimized .. but it is truly data-only, afaik. It is also based on IP. So I don't see how an IS95 phone with circuit-switched data capability can receive data service on a DO IP network. Looks like forward/backward compatibility may stop at the DO line. Actually, a DO phone may be able to obtain data services on cdmaOne and 1x networks. Can somebody help with this? Ron
