Before I upgraded my HD, I deauthorized all my iTunes accounts. Once the new HD was in place, I imported everything from my old HD and authorized all my iTunes accounts on the new drive. I was able to sync my iPod to the new setup without incident. Here's where the problem begins. The iPhone didn't immediately tell me that it was synced to another machine, the way it did for the iPod. Long story short: my iPhone show the greyed out settings for how it is synced to the old drive, and most of the apps have disappeared. Does anyone have any idea how I can get this working again with my new drive?
