Microphone working intermittently during calls (beta 3)

[austin.e.ma]

I just recently got a replacement phone and the microphone randomly chooses when it wants to work during calls. Sometimes it works, sometimes it doesnt. I can always hear other people just fine but they cannot hear me. I know it is not a hardware issue because the mic always works fine within apps that use the mic. I am running beta 3 and I did not get a chance to see if it worked fine while running 4.3.3 so I do not know if this is a ios 5 issue or my phone.

Any suggestions?

I am currently trying to downgrade to 4.3.4 to see if that is the problem but I am having some difficulty

Hi sounds like you have the same problem as me. When I went to install the latest OS my phone bricked(error 14).So I went to apple and got a replacement. Have had trouble since cant seem to sync my music back. The phone works fine at apple so mayb there is a software problem on your pc side. Which I am trying to fix on mine too.
