ICloud – How to turn off icloud when no account has been set up by me

It seems that it may be tied to the Fetch New Data setting in Mail, Contacts, Calendars.

When I change that setting to Push, the bookmarks are sent out straight away.

What I don't understand is why the Photo Stream pushes out changes immediately, even if 'Fetch New Data' is set to 'Every 15 Minutes', but the Bookmarks (which appear to have nothing to do with 'Mail, Contacts, Calendars', are not.

Later:

I've just seen the "Advanced" setting in "Fetch New Data". This seems to have a manual override

With Fetch New Data set to "15 min", (and Push is Off), and iCloud set to "Push", I expected to have the bookmark pushed out straight away.

But this doesn't happen: I also have to turn the main "Fetch New Data" setting to Push, in order to have the bookmarks updated immediately.

One new feature of iOS 7 is an activation lock - and this means that you can't sign out or erase the device without entering the proper password for the account to which your device has been locked.

Towards the bottom of the article, it has a link to use My Apple ID web page to check and reset your password if you have forgotten it.

Presumably, if you can't reset the password, you might need to reach out to Apple directly and see if there is an administrative process such as mailing them proof of purchase or correctly answering questions about past billing events to have them reset the account password.
