I need to access /library on iOS 5.1.1 from a PC without jailbreaking
===

I know that this might be useless, but I just wanted to ask.

I have an iPhone 4s running iOS 5.1.1, a few months ago my wife did set a restrictions passcode on it to prevent our daughter from changing some settings accidentally while she's playing games with the phone.

Now my wife forgot that code and needs to change some settings herself and of course she's not able to do so.

I've got a way around this but it's necessary to access /library/keychains to do it.

Since the phone is not jailbroken, I can't access that path (Using i-Funbox)

Is there any other way that I can use it to access this path ?

Is there any way around to reset this passcode ?
