It’s never fun to accidentally delete a contact that is needed, let alone multiple contacts or even an entire address book.

After my later trying, I’ve come to the conclusion if you have used encryption for backups, iTunes will not allow you to start a completely new backup with a new encryption password unless you know the previous password. While, I now find lost iPhone 5 backup password easily with software iPhone Backup Unlocker.

If we usually would save our kinds of passwords used as a file, the mode would be the right choice: Dictionary Attack. If unfortunately we could not recall anything about our password set before, we should choose Brute-force Attack. I got suggestions from website that supports professional iPhone Backup Passowrd Unlock tool.
