Issues with iPhone 4 with music, apps, photos, etc. My iPhone 4 has never been synced to a computer but has music and stuff on it.  I'm scared that if I sync it to my new computer I'll lose my contacts, music, etc.  Does anyone know what happens when this is done?
There's absolutely no problem in syncing your iPhone with your new computer: your data will just get copied onto the desktop, but will stay intact on your device.
