Another LTE network turns up as IPv4-only

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.
