Hi,

T-Mobile USA has native ipv6 to all subscribers in all of it's coverage
area. But, less than 1% of subscribers use IPv6 because they do not have an
IPv6 capable phone. The Nexus S and Galaxy Nexus work well.

This device challenge will improve in time.  Samsung is doing a good job of
bringing IPv6 to Android devices. More info here

Yes, NAT64 / DNS64 is used in the case of reaching ipv4-only nodes.  If you
are concerned about middleboxs, you should deploy IPv6.

Small today. As IPv6 becomes the default setting, that will change.
