volume icon stuck in middle of screen?
Out of the blue there is a volume icon stuck in the middle of the screen of my 3gs iphone. I didn't make any changes to the phone. This speaker picture stays on all the time, no matter what I do. It is an overlay on top of everthing, making it difficult to use the keyboard, text, everything has this picture of the speaker in a gray box right in the middle of the screen. Does anyone know what it is, and how I can get rid of it? Thank you for your help!
