I apologize in advanced for my stupid question, but I can't wrapped my head around something. So Wi-Fi Sync will allow me to sync my iTunes library with my iOS device. How exactly do you decipher what exactly you want to sync? (music, movies, tv shows, ringtones, apps, etc?) Also, I have a 50 GB music collection in iTunes but a 32 GB iPhone 4. So what happens here? Will it add music until it runs out of space? Are there settings within Wi-Fi Sync? (I'm assuming there are.) Again, I apologize for my stupidity.
