Okay guys, for some reason the only way I can hear people from the other side is if they are on speaker phone. Does not work any other way, even tried my bluetooth headset and it cannot find my iPhone. Everything was fine until I hooked up my iPhone to my new Stereo (Panasonic Head Unit with USB). After that I noticed that's when it started to happen. I've tried doing a restore, putting the phone into recover-mode and putting it in back to factor settings and unlocking it with ZiPhone and still it doesn't work. Any suggestions guys?
