Title:

Mic Not Working - No one can hear me!

Text:

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!!!
