Hello, my friend has had an iPhone 4 for ages and has never updated it. It currently has IOS 4.3. She would like to update to IOS 6 but she doesn't have a computer. She has never connected her iPhone to iTunes. Can I connect her iPhone to my computer iTunes in order to do the update? Is it ok even if I already connect two other iPhones? Will she keep her own apps, music and photos?
