I have not had those problems with my Tour - callers have said it sounds better than my Pearl did.
However, I did have some weird UI problems with my iDrive BT and my Tour... the other day I couldn't receive or make calls from iDrive. Phone Book presented, but Call was ghosted out, and no Answer screen would appear with incoming calls. I could initiate and answer calls from my handset and BT handsfree worked fine.
I realized I hadn't had a hard reset in over a week, so I battery cycled the handset when I had a few minutes, and it's been fine since.
Boy Genius Report says an OS turn for Tour is in beta for VZW as we speak... won't be soon enough for me
