Hello, I have a problem with my iPhone 3G. Audio (speaker, headphones, microphone) stops working without reason till I reset to default. It happens every day. When I plug in headphones it doesn't recognize they're plugged in. When I try to use skype it says no audio hardware available. I tried: - plug and unplug headphones several times - restore with and without using backup - iOS 4.1 and 4.2.1 - reset to default settings (which works but I can't do it on 2-3 times a day) - restart multiple times Thanks for suggestions!
