I spent 75 minutes at the Genius Bar last Friday. It turns out there was some historical conflict with Entourage (which I hadn't used since 2008) and my iPhone, which I started using in 2011. In the end, the solution involved deleting a bunch of preferences, then open and closing Entourage. All is fine now. thanks Apple Store!
