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.
