Callers cannot hear me through the phone mic. They can through the speaker and if I plug in a headset, but not through the normal phone mic. What is the problem and is it worth fixing or just buy a new phone?
Sounds like the Mic has failed replacements are available HERE and HERE Replacing the iPhone 3GS Dock Connector may be the easier option though (contains the Mic)
Hi, I’ve the same problem, callers can not hear me even with the headphones, but i can record my voice, it works great. If I change dock connector, is it work? Thank you
