After upgrading my wife's 5S from 7.x to 8.0 an ICON which I don't recognize is on the phone and can't be deleted. Touching it runs nothing, it has no name attached and when I select DELETE to delete it nothing happens. Does anyone recognize what app it might be or know how to remove it? If I knew what it was I could properly install it then delete it. I looked through ALL my wife's app store purchases as well as mine including what was not on our phones and iPad and can't find it. This is the "MYSTERY" APP. Look familiar to anyone? If I select DELETE nothing happens.
