So. With a green-field deployment, in their home market (supposed to be the first of their tree-digit million subscribers world-wide to get all the cool new tech), built on 3GPP specs that fully supports IPv6, already proven to work by other pioneers (^5 VzW), for which there are plenty of compatible devices (again, ^5 VzW), and plenty of compatible content (^5 ISOC, et al.), four months after World IPv6 Launch (in which they participated), and one month after their RIR ran out of IPv4 addresses...launching without IPv6 support was a perfectly natural and sensible thing for them to do, it seems.
The problem I have seen is not to get IPv6/dual stack in LTE (this worked from day one), it's to get dual stack working in all the cases with bearer establishment and handover between 2G/3G and 4G.
2G/3G is "fully integrated" with each other, but LTE is still kind of separate, vendors are just now getting around to producing mobile core nodes that support all of them with a single node for each function.
Would you want to get IPv6 when you're in the LTE network but lose it when you were handed over to 2G/3G. My guess is not, so I believe providers will wait until that is really done.
