Restoring your most recent iPhone backup can recover any deleted notes. Your notes are restored to the Notes app whether you use iCloud or the iTunes program on your computer as a backup resource. Use your iPhone's Restore feature to access and restore an iCloud backup over a wireless network. If you use the desktop version of iTunes to back up your device, use the Restore From Backup feature to retrieve your deleted notes.
You need to back up your iPhone before you can use the iCloud or iTunes Backup feature to restore your deleted notes.
