Mobicip offers parental controls for all smartphones/tablets, etc. but I know the iPhone can be locked down pretty well too. I'm currently using Kidsmail for my 10yo ds' email he recently asked to have. I receive copies of all incoming and outgoing emails without having to check. I can also deny a message getting thru to him which I did one which I did not recognize and seemed like phishing. Netnanny is another one though I'm not sure what it's full capabilities are. None are free.
