How do I fix the sound on my iPhone 4?
I was facetiming my friend earlier when the sound just shut off all of a sudden. I hung up on her, then turned it off and back on, checked my music, then my sound settings, and I will get some low, kind of scratchy sound. but if I turn it up any higher, the sound just completely stops. yes, ive reset it, hard reset it, blah blah blah. help?
