Chaz,

<< is very comprehensive ... also not very current >>

Yes, 2 months is pretty old in CyberTime. I sure would like to see something dated today that is as comprehensive.

<< One point that caught my eye was that Ovum is predicting that one major option will be a handset which covers GSM, CDMAOne and CDMA2000 >>

It sure caught mine since I am a VodaBam (Verizon) subscriber who travels in Europe and other GSM strongholds where CDMA is virtually nonexistent.

<< CDMA2000 will work with both CDMAOne and GSM? >>

If it is going to have to if it wants to survive in a mobile world committed to global roaming.

Today a Vodafone customer has one roaming option when traveling from Europe or Asia to the US. Rent a GSM handset and use his SIM, taking advantage of Vodafones roaming agreements with GSM NA partners.

A BAM customer has very few roaming options traveling outside the Americas (unless to Korea or Japan). Actually, come to think of it, I'm not sure they have roaming agreements there.

Me, I own an old Bosch Worldphone, and use an Omnipoint subscription. I'd like to ditch the extra phone and the extra subscription.

I am curious since some here seem to think that GSM and CDMA2000 are repellant forces sort of like magnetic polarity. Perhaps that fear is a bit overstated.

GSM and CDMA2000 use incompatible call models.
(A call model defines - amongst other things - the message exchanges between the handset and the basestation during Registration; Call Set up; etc. The call model is implemented by the protocol stack.)
