iOS 7 keeps turning on Restrictions

Yesterday, I was shocked to find Restrictions turned on in my iPad. I have not used Restrictions since iOS 7 now locks out the ability to disable "Find my iPad" without dealing with Restrictions. Furthermore, and more troubling, was that none of my known pass-codes worked!

Today I was able to reset and disable restrictions with the following help:

...Refers to this post containing the actual fix:

(It is essentially an edit to springboard.plist adding a "SBParentalControlsPIN" value of "1234." This is documented in several other places so I will not get into more details here.)

Like others on the thread, I was a bit dubious on how restrictions (which again I have not used since iOS 6) were turned on in the first place.

However, now my suspicions are confirmed: About four hours after Restoring my iPad and turning off Restrictions, somehow they turned back on, again without any pass-codes that I know! I have not let my iPad out of sight, and I am positive I did not turn Restrictions on during this time.

I will of course go through the fix procedure again, but what could be causing this? Naturally I cannot yet Jailbreak iOS 7, but I also never jailbroke my iPad at any time - but could some rogue app be doing this? (Remember it attempts to turn off "Find my iPad" and locks the ability to turn it back on.)

iPad Mini (first gen - AT&T (USA) 32GB)

iOS 7.0.4

Oh, and my iPhone 5 (also first gen - AT&T 64GB on 7.0.4) connected to the same iCloud and containing essentially the same apps does NOT have this problem!

Does anyone have any ideas on this? I do not like the proposition of having to Restore my iPad every single day in order to continue having full-access to my iPad!

Thanks much in advance!
