I have a friend that accidentally deleted sms from its iphone, and would like to restore the backup to have them back. The problem is, the backup is encrypted and he doesn't remember the password. We have full (jailbreak)access to the iphone. Is there a way to recover this password from iOS? I got the keychain-2.db file, and there is a row for the backup password, but no password... I also know about Elcomsoft paid software,but that is the last resort.
