Mic Not Working - No one can hear me!
I have an iPhone 3G 8gb that is unlocked and jailbroken, running on 4.2.1 with baseband 6.15.00. Everything is working except for the mic. When I make or receive phone calls, I can hear the caller but they cannot hear me. However, if I blow into the mic...they can hear that. I have opened the phone up, checked and cleaned all connections. After putting the phone back together and trying a phone call - it WORKS...but only the first time! The next phone call made - same thing happens - the caller cannot hear me. Sometimes there is an awful buzzing noise...like a bee hive. LOL I have replaced the dock several times but the same thing happens. I have done a hard reset, restored the phone and then re-jailbroke and unlocked it - nothing seems to work. This phone hasn't always been like this...it worked great when I first bought it (used - on eBay). However, a few months back I replaced the digitizer and the back housing and also did the update to 4.2.1... and ever since - I've had this problem. Help!!!!!!
Update! 10/7/11:
Still having the SAME issue! I have taken this phone apart I don't know how many times now trying different things. I even opened up one of my other iPhone's and checked every single connection, every last screw, cable, etc...just to make sure I wasn't missing something or that something didn't look broken. EVERY SINGLE OTHER THING ON THIS PHONE WORKS! It's driving me nuts!!! I don't know what else to do. Can anyone help????? I was able to plug in the phone with the cable to a wall outlet and when I tried the "Voice Memo" to see if it would work....it did...then when I tried it again - it wouldn't work! The only thing I could hear was myself blowing into the mic. I'm so confused!!!

When did the mic stop working? After the repair? Jb? 1st time you used it or gradually over time? Might be connector 4 pin or one of the small inductors. It could be 4.2.1.. Lots of could be's... Let's see if we can narrow it down.

Thanks for the response! When I first purchased the phone (through eBay...seller refurbished) the mic worked fine. A few months back I replaced the back housing, the touch screen, and the home button. Shortly thereafter is when I upgraded to the 4.2.1 with 6.15.00 baseband. I want to say the mic stopped working BEFORE I upgraded. It's so strange because when it first started it was only on some phone calls where the caller would say that all they could hear was a "buzzing" sound. Then the phone would work normally for awhile. I just keep thinking if it was a bad mic, wouldn't it just not work at all? Also, if I blow into the mic, you can hear that. I did notice tonight a few creases in the cables near the headphone jack and wifi antenna (cables #5 & #6). I've ordered a new part to replace that but I don't know if that section of the phone even has anything to do with the mic. If you have any ideas that would be great!! Thanks!!
