Another aggravation regarding IPv6-only APNs on iOS is that an unlocked iPhone is unable to use an IPv6-only APN. The only way in iOS to control the type of the APN is with a provisioning profile, and these are not used on unlocked phones. Maybe one of the carriers with sufficient influence with Apple Core OS Engineering that their demands have some hope of sticking could complain to them about this? It’s the reason I can’t use IPv6 APNs when I’m traveling on a foreign SIM card. I know, I know, like there is such a carrier who has any interest in seeing unlocked phones have any more useful features.
