iPhone backup

Did she have automatic backup to iCloud setup? Do that and if you ever need a new phone you'll always have the latest and greatest to restore a new phone from. You can also do a backup to a computer at any time as well. I've done this probably 4 or 5 times with iPads and iPhones and it works seamlessly every time. When you get the new phone, in the setup there will be options to "Set up as new" or to "restore from a backup" and you'd restore from backup by either plugging into a computer to use the file or if you have it in the cloud, you can do everything straight from the new phone. All settings, contacts, apps right back exactly how they were.
