Lost or forgetten iPad Restrictions PIN code

A client called having forgotten the 4 digit PIN code to access the Restrictions menu on one of the restaurant iPads. This used to be stored in plain text in one of the files saved to your computer backup by iTunes.

Its still in the same file now, its just encrypted now. There is a crack for it here

An extra tip - that 398bc9c ... etc file is a bit hard to spot in the directory. The easiest way on a Windows PC is to click once on one of the files in the directory, so its highlighted. Then start typing 398 and it will quickly jump to it, right-click and use Open With > Notepad

This saves doing a full wipe and reinstall of everything, just to reset the Restrictions code.
