How to circumvent a forgotten encrypted iPhone local backup password? I forgot my Encrypt Local Backup password for iPhone4S.

I tried to transfer contacts, photos, etc. to my new iPhone5 through iTunes with operation "restore from backup" but it always asks for a password that I can't remember.

How I can transfer contacts, photos, etc. to my new iPhone5, or do I have to enter all contacts manually?
I knew that you need the backup password to get your contacts, photos, videos, etc. I have the same situation before. You can find a tool to unlock the backup password, or go to Google Search: "iPhone Backup Unlocker"
