I remember a few weeks ago i was able to turn off the headphones. I selected the little headphone icon that appears on the top notification bar when the headphones are in plugged in and somehow turned the jack off, don't remember much more than that. When I was trying to listen to music today no matter what headphones I have plugged in, the phone acts like there aren't any and plays through the speaker. I went to the fm radio and on 3 different headphones being plugged in it would tell me "please plug in headphones to use fm radio" or whatever. I can't find a setting for it anywhere and the tech support had no idea.. Please help ... please
