Forgot Restrictions Passcode

As this article states, you will have to erase the device and set it up as new to remove the passcode.

About Restrictions (parental controls) on iPhone, iPad, and iPod touch - Apple Support

Hi

This is the same passcode you use each day to switch iphone on.

If you cannot remember restore iPhone on your PC in itunes .

Cheers

The restrictions passcode is not the same as the iPhone passcode.

The title as well as the body of the original post refer to the restrictions passcode.
