I have a problem I haven't seen addressed anywhere here yet.
After upgrading to 2.1, everything seemed to work fine. But then I got a call last night and answered it, but couldn't hear anything. And apparently, the person on the other end couldn't hear me. (This was shortly after receiving a call that I had no problems hearing, and I don't believe I played with the settings at all.) Tried again two more times and same thing. We were connected, but no one could hear anything.
I restarted my phone, and it began working fine. But this morning it happened again. (I also couldn't hear a message I was trying to play back in Google Voice.) I restared and again that fixed it, but obviously I don't want it to keep sliding into silence. Does anyone else have this problem? Any ideas how to fix it? I'd like to keep 2.1 if possible, but if this keeps happening I'll just downgrade to 1.5. (Sigh)
