4.2 Update: Continued

Now that I have told you about the bug and how to fix it, I will include a picture to show you just exactly what may happen to your device when you update it. It happens to others, but it also doesn't happen to some people. It did happen to me when I updated my iPhone 3G, but all I had to do was start playing some music from my "Purchased" list, synced my iPhone, and voila! They were back!
