All of a sudden my mic stopped working. Also external headset mic doesn't work. Only bluetooth headset is ok. I've replaced the headset jack, that didn't fix my problem. The phone is not stuck in headset mode. I've doctored it, went back to previous 2.2.3. I've created a new profile. Also tried to use ghastly headset to force out of headset mode... Nothing seems to fix my issue. Any advice what to do???
