2 of my kids have ver 4 ipod touches and I want to update them to ios5. The problem is they were not originally set up with my computer...what options do I have so that I don't lose all their music etc? I asked this on another site and got this answer... "You can plug them in and update their iPods but first prevent iTunes from syncing with their iPods or their music will disappear. In iTunes go to Edit, Preferences, Devices, check the box that says prevent iPods iPads iPhones from syncing automatically.. 99% sure on this." Any help? Thanks.
