Has anyone had success with tier III support enabling these features on a compatible (just not AT&T sanctioned) device? I'm a bit preturbed that the AT&T BYOD page, when putting in the IMEI of my new Sony Xperia Z5 (E6653) says "Congratulations, your phone is compatible" in big bold letters .... but
