I think that in most cases a bug can only be fixed with a future update. As for the customer service problems, it could just be that some people are taking a much needed vacation and they're a little short-staffed right now. I have to think that there is a lot of work leading up to and directly following a major release. That of course is just one other guess.

Personally, while I've found an occasional hiccup, I am very happy with this release. The RTs sound better than ever!
