So maybe you guys can help me narrow this down. I replaced the dock connector piece of the iPhone, the part that includes the dock connector, speaker, mic, home button, etc. because my home button wasnt working and it wouldnt charge. So now just about everything works, except for the microphone. Do you think maybe the part I bought from ebay could have been bad (even though everything else works perfectly) or could I possibly have missed something when replacing it? Has anyone else here ever actually taken their iPhone apart before?
