And what are your results? Does your data and connections seem faster? I created a new APN profile to test it out and maybe it's just a placebo but I've noticed that during speed tests, either through Ookla or Sensorly, my results are anywhere between 2mbps to 6mbps faster than on IPv4. I'm using an M8 which is supposed to be IPv6 by default but mine was IPv4. I have LTE in my neighborhood but when I'm in my building, I only get HSPA. So in my case, this change was actually for the better. Anyone else try this?
Here's a list of devices that can use IPv6 and how to do it - https://sites.google.com/site/tmoipv6/lg-mytouch
