Went by two AT&T stores to find out what the icon was.
The first person told me it was a new icon for their updated service which I had my suspicions about.
Checked the main outlet and the girl took one look and said it was a calendar reminder. About two weeks ago I had set my next year doctor appointment and forgot about it.
Turned the reminder notice off and the icon is gone.
At 72 I am having more of these senior moments(brain farts).
