My iPad 3 on iOS 5.1.1 freezes every time I plug in my apple headphones and try to use them. Listening to music or starting video, nothing happens and the Pad freezes. It "revives" back to normal when I unplug them from the Jack. Very frustrating! I dont believe this has been a problem all the time I have had the iPad. At least I think I remember that I have used them without an issue before. I have tried two separate apple headphones. Freezes with both. Anybody heard about this issue before?
