Answer to: Can hear conversation on speaker onlyI recently opened up my 3GS to diagnose a silent switch issue and have a similar problem. I think I may have damaged connector #3. There was nothing in the "How-to" that made connector #3 seem of any importance. I have a theory that connector three is a link for the ear-speaker, but the speaker-phone mode plays through the speakers adjacent to the dock connecter and doesn't need connector #3. Can anyone back me up? Or help us both with a fix?
