So I'm curious how the mobile operators deploying ipv6 to the handsets are dealing with ipv4. The simplest would be to get the phone a routable ipv4 address, but that would seemingly exacerbate the reason they went to v6 in the first place. Are carriers NAT'ing somewhere along the line? If so, where? Like does the phone encapsulate v4 in 4-in-6? Or does the phone get a net 10 address and it gets NAT'd by the carrier?

It seems also for mobile carriers there is incentive for as much transit as possible for native v6 to the servers. Or is the deployment of v6 mainly within the carrier network itself and it's NAT'd somewhere?

Basically what does a typical v6/v4 architecture look like for a mobile carrier these days?

Agreed. When they have to connect to an IPv4 only host, they do some type of AFTR. These devices have never known a world outside of this situation. That is a major difference.
