Restrictions Page Passcode?

[joegraz]

I just discovered this page and I'd like to make some changes, and I'm being asked for a passcode. I know for a fact that I've never set a passcode and I am unable to get in. Is there a wildcard preset here? If not, how can I retrieve passcode? Thanks in advance!

if you don't know the passcode your only real option is to wipe the phone and start over
