Yesterday I was using my iPhone as an iPod with the factory iPhone earbuds. It was acting strange because I couldn't turn the volume all the way up with the side buttons, only through the touch screen. Anyways, later that day while trying to watch a youtube video, there was no sound. I reset my iPhone, same thing, no sound when unlocking the phone, ipod or youtube. Any ideas of what went wrong? I plugged in some earbuds and that works perfectly, but when removing there is no sound from the speaker. What makes this really weird is that when I get a phone call the speaker works fine. Thanks in advance.
