NOTHING IS PLUGGED INTO MY IPHONE! Yet while im on it, every single minute a message comes up saying that my device is not compatible with this thing, put it into airplane mode. I have nothing in my iphone. I turned it to airplane mode and still had the pop up. I got it out of airplane still had it. I turned it off and then on and still got the pop up. HOW DO I GET RID OF IT
Try something simple first, dock it to something that actually wants it in airplane mode. Then undock it and see if that cleared up the problem. Or just put it in airplane mode, turn it off and back on, then get out of airplane mode. Sometimes these devices get stuck in stupid mode and need a nudge to get back to normal.
On topic: I agree with what nickels said. If that doesn't work, restore. Or you could always go to an Apple Store and see what they say.
