I know we can password lock the iPad, but how do you secure your iPad setting as that's the heart of iPad? I had my mail set up in iPad and I can turn it off to prevent others from peeking into my mail by doing it in setting. However, if anyone wants to peek, they just need to go into setting and turn it back on. Apple obviously forgot to create a password lock for setting as anyone can access anything once they pass the initial password lock. Is there a third party iPad software that can do just that?
