Restoring a backup is one way to read a deleted iPhone file.

If you accidently deleted a note, an important contact or a favorite photo on your iPhone, all is not lost. Provided you don't mind a little work, you can find that file and access it. If you made a backup, you can restore the backup to get access to the file. A second option is to use a third-party utility to find the deleted file on your iPhone or on an iTunes backup.

Restoring a Backup

Provided you made a backup on either iTunes or iCloud before you deleted the file, you can restore the backup to make it accessible again. To recover an iPhone backup, connect the iPhone to your computer and select "Restore Backup" from the iPhone's Summary tab in iTunes. To restore an iCloud backup, launch "Settings" on the iPhone's home screen, select "General" and then "Reset." After you select "Erase All Content and Settings," you will be prompted to restore from the iCloud backup during the setup process.

Using Third-Party Apps

Third-party apps like Tenorshare iPhone Data Recovery give you the ability to read files on the iPhone even after they have been deleted. The same software can also access your iTunes backup files to help you find the lost file there. Install the software on your computer and follow the onscreen prompts to locate and recover your deleted files. Note that this may not be possible if your iPhone has overwritten the files with new data.
