Lakers,

<< Another question for you, how does WCDMA, the so-called GSM revolution, achieve that interoperability?:-) >>

By virtue of the voluminous 3GPP 'R99' UMTS Standard, which is backward compatible with the GSM standards that preceded it in many respects, and goes well beyond the more than several various USIM standards that it contains, which facilitate "dual-mode".

Eventually Qualcomm will need to deal with this in their WCDMA chipsets. Initially at least, they are OK for Japan, since at least in initial implementations DoCoMo will ignore this backward compatability to GSM since they have no GSM base. Europe and elsewhere will be different.
