And this is where government regulation would have helped. It's a shame nobody listened to me back in the 90's: (it's a joke. I'm a nobody, there is nobody listening.)

All cell-phones should have been ipv6 from the get-go.

Now if we could just go back in time and warn everybody about IPv4 address space being exhausted. And maybe the climate too while we are at it.

Seriously though, cell-phone adoption would make that a game changer. Hey Apple, sell it as an exclusive feature!
