TTBOMK, that isn't *quite* true, yet, Owen. The only US carrier with LTE deployed is VZW, and their only *handset* with LTE is the not-yet-quite-shipped HTC Thunderbolt... and it is my understanding that their first generation release of handsets will *not* be doing PSTN voice as VoIP over the LTE data connection; they'll be dual-mode handsets, using traditional (IS-95? IS-136?) CDMA voice on a separate RF deck. The two reasons I've heard have to do with battery life and the immaturity of the protocol stack or its implementations. LTE-data-only with VoIP for the carrier PSTN service is indeed their goal, but I don't think you can say "Already are" quite yet. Cheers, -- jra
