this has been bugging me for almost 2 years. When I switched iPhones my music did not transfer and I could not figure out how to get it from my Mac to my iPhone. I finally did a little research and downloaded iTools and that took care of that. For some reason I still could not get it to work through iTunes but this works just fine. And soon it will be time for a new phone. This time I won't wait 2 years.
