IPv4 shutdown in mobile

Does this mean you are negligent for not supporting IPv6 on my phone on your network?

My phone is perfectly capable of IPv6, yet because it doesn’t support your particular religion

When is T-Mobile going to fix their IPv6 implementation and stop ignoring the #1 market
leading phone manufacturer?
