I have a 3GS 16gb. Everything was fine, until it wasn't, )). I did not add any apps in the past two weeks or so, last night I made three new ringtones out of songs in my library. Today I tried to play some music and there is no sound, I look closer and see there is no volume bar anymore. Try to play video, same thing. I have one app (stone-loops) tried to play that, it plays but no sound. The phone rings, but when I get a text it only vibrates, again no sound. Put in ear-buds, the volume works, sounds comes out and there is a volume bar like it should be. When I take out the ear-buds the sound goes off and the volume bar disappears. I have tried reset several times, but nothing helps. Any ideas?
