My sound stopped working this morning. No sound from the ringer, any video or apps and IPod. Headphones work fine and I can hear phone calls but no sounds at all from the phone. New 3G, never dropped or wet, not a ton of apps and nothing new added that might have changed anything. I've tried all the reset/reboot, cleaning the headphone jack, etc. Nothing, seems like a software issue and I'm willing to try whatever since my warranty is up. Help would be very appreciated! Thanks.
