Peter, re "And just how does the handset multi-home between GSM and W-CDMA without network assistance?" I'm not sure what you mean by multi-home. Sounds like it would be related to receiving calls. IOW, the network needs to know physically (geographically and spectrally) where to terminate the call. It is my impression that, in general, the mobile (handset) lets the network know where it is. Consider two simple cases. You turn on the power of your dual-mode GSM/WCDMA handset (1) in an area served only by a GSM network, and later (2) in an area served only by a WCDMA network. You expect to receive voice calls in either case. The handset needs to communicate with the radio-access-network ("RAN")in both cases. To do so, IMHO, it searches through a list of possibilities that are stored in the SIM. Let me clarify my original point. If the WCDMA network were truly backward compatible, you would be able use your GSM-only handset in a geographical area with only a WCDMA network. You wouldn't have to buy that dual-mode GSM/WCDMA handset. Regards, Ron
