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.
