I just brought my new iPhone 4 home, and started syncing it. To my chagrin, I realized that I have more music than the 16GB can fit. So, I unchecked all of the tracks that I don't really listen to. Unfortunately, I can't figure out where to tell the phone to only sync the tracks that are selected. I remember this used to be pretty easy. Please let me know, I would appreciate your help. Otherwise, it's a pretty fun toy.
