Can the phone and ipad IOS be updated without syncing with Itunes library? We had a robbery and I lost my laptop and the external HDs that was with it. SO right now trying to piece my library back together but would like to update the Iphone and Ipad to latest IOS but dont want itunes taking my songs and stuff off since Im missing alot atm. Sucks having your back up stolen also. Thanks for any help.
