The icon on the left of the stats bar icons showed up yesterday and hasn't gone away despite several reboots. I've never seen I before and it isn't the same a any icon in my manual. It looks like a headphone plug but I don't have anything plugged into the phone at all and the actual headphone icon is different.
Any ideas what the icon is and how I can get rid of it?
For clarification its the first icon to the right of at&t
