Hello, I was curious if anyone uses call forwarding and/or call-waiting with AT&T? Using an iP6+ and noticed when I turn either option on-- exit out and then go back, it is off again. Further, when I try to enable call forwarding it cannot update/fails to update. I also tried the **21*num# method and that way fails too. Was curious if anyone had seen this before? - I've tried resetting network settings and to no avail. AT&T said they have never heard of that problem before. Thanks, Justin.
