Internal Mic doesn't work, even after replacing dock assembly
So, my iPhone 3G had a shoddy mic which would work when only you squeeze the phone. Thinking it was the connection, I resoldered the mic and it was fine for like an hour, so I decided to buy a new dock connector assembly to fix it permenently.
The iPhone headphones work fine--when plugged in I hear sound and I can use that mic. When they're unplugged, the built-in speaker works, just not the built-in mic.
Anyway, I installed the new dock connector assembly, but the mic now doesn't work at all. The actual dock connector and speaker work fine, and the mic built into the headphones works.
I am wondering if there is some trick to getting that piece installed that would affect only the mic, or is there anything I'm overlooking? (I did pull some lint out of the headphone jack, but it didn't help).
Thanks for any help you guys can give
