Note that in Android 4.0 does not believe it has network if it has only IPv6. (This is sadly, not fixed in 4.4; there are some structural hassles to testing it for many, thus hard to know if you succeded) Android 4.0 certainly does work DualStack. This is a result of not accepting DNS servers via RDNSS (nor DHCPv6), and believing that it can not operate without DNS (which is probably logical). > supporting it pretty well.

Whether Android works or not on IPv6-only over 3G, I can not speculate, as sadly, I haven't got any way to test that. https://code.google.com/p/android/issues/detail?id=32630 -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works -= IPv6 IoT consulting =-
