Okay, so a while ago I set a restrictions pass code on my iPhone 3GS because my little sister would always take it and buy apps/songs without my permission.

But, I forgot my restrictions pass code and can't reactivate my iTunes/App Store.

I tried restoring it (like many help sites said to do) but that didn't work. However, after I restored it, I backed it up so that all my old info was on it again. Am I supposed to restore it and NOT back it up so it starts brand new?

NOTE: restrictions pass code is NOT the same as the unlock pass code; restrictions pass code is for blocking stuff like safari and the app store.
