Dear Charlie 42,
As we know, every time you sync iDevice with iTunes, it will automatically make a backup of your iDevice contents including photos, SMS, reminders, contacts and more. Therefore, as long as you have ever synced your iPhone 4/4S/5 with iTunes, you can get the lost messages from iPhone 4/4S backup files created by iTunes. Sounds greats, isn’t it?
To restore lost messages from iTunes backups, you need:
Do not connect your iPhone 4/4S/5 to iTunes again until the messages are recovered. Otherwise, the old backup file will be overwritten by the current content on your iPhone 4/4S/5. Once it happens, the deleted messages will be gone forever.
In addition, iTunes backup files cannot be used and opened directly on Mac and iDevice. The backup files location is “~/Library/Application Support/MobileSync/Backup”. In Finder, press “ALT/Option” on your keyboard and click “Go” from menu bar, you will see “Library” option. Choose it and then you can find the backup files.
How to use iTunes backup files to restore deleted messages?
Data Recovery for iTunes can get back your lost messages, photos, contacts and more on your iPhone 4/4S from iTunes backup files. If you accidentally lost your iPhone 4/4S/5 or deleted some messages off iPhone 4/4S/5, with this recovery utility, you can restore them at ease. No need to connect the devices! No need to open iTunes!
