Restrict Unblocking Contacts by child
My teen can easily unblock contacts that I have blocked using a RESTRICTION code. I have also selected "do not allow changes" for Accounts and Contacts under the Restrictions menu. In fact I have disallowed changes on most everything available. Even after this, the block/unblock option is still available under her phone list, contact list and imessage list. I realize these are all the same list just letting everyone know I have checked via every possible way I can think.
Any help is appreciated. I desperately need to eliminate her contact with a few "friends". I've spent a lot time trying to figure this out and am ready to replace her iphone with a basic flip phone.
