iPhone 4 No in call audio!!!

[dopeytree]

Hi everyone I updated my iPhone 4 to the iOS 6 beta. I have a gsm phone.

Now if I receive a call the ringtone fires but I get no audio in call and they can't hear me either!!! This is a terrible bug. The mic works fine recording video etc and was working right up until I upgraded the software.

Has no one else encountered this? If not then I will reinstall

I had this exact problem. I restored twice and it worked the second time.

I had this exact problem. I restored twice and it worked the second time.

I thought it is a bug in iOS 6 too.
Fixed by restoring to iOS 6 again, or 5?
