They also felt that anyone who couldn't graft an MMI onto their stack was retarded. They must have been referring to NOKIA, LOL!

molloy, looks like you may still be confused with what G* can do, in which I'm talking about the G* mode, not the terrestrial mode. Currently G* mode itself can talk to both IS-41 or GSM mode. G* Gateway itself is a little everything that can handle the both. In G* air interface, UT can determine which mode it need to use, again don't confuse this with terrestrial mode(I suggest let's forget about the terrestrial mode). However the physical layer is still using CDMA technology as the way for transmission. The divergence occurs above layer 2(link layer). In GSM part, G* can do that Radio Resource Management, Mobility Management and Connection Management, while in IS-41 mode it is handled by the Call processing layer. So as you can see, Q can do the higher layer GSM already, this is not only on the phone side, but also on the infra side(in Gateway, which is connected to the GSM-MSC via SS7). Now about the radio side. It's not hard to believe that the 1x/GSM can go the same route. Only this time the link layer and physical layer need to be changed so that it can really talk in GSM on the radio side. As you may or may not know, Q also had very good background in TDMA technology, in fact a lot of them when they were working in the UltraPhone with SCS. Don't assume Q knows nothing about TDMA. As for the question about the need to license GSM IPR, as I said you still need to actually talk GSM/TDMA on the radio side so you have to license it EVEN if you know how to do it. Partnership can also help too. Although one thing is different in 1x/GSM and WCDMA/GSM is on the network side. WCDMA is designed to be talking in a GSM fashion, is having its network side designed to do so while the CDMA2000 is for the IS-41. So in order for the CDMA/GSM be usable, changes must be made on CDMA BSC. On the other hand in order for the CDMA/GSM to have the interoperability, GSM base station will also need to have some features being added in so that the phone can roaming back and forth seamlessly. But make no mistake, that kind of change is also needed even using WCDMA. As I can see, the harmonization is the king, just like internet can connect different networks together. The trend of cooking a little everything together via this multimode thing will be getting stronger and stronger.
