I saw a story on the news similar to what happened to you. It seems that when you enter your password....someone can still download things for 20 minutes AFTER that time without entering it again! So....for instance...you are just doing updates to your apps and you enter your password, then you are finished. Your kid picks up your phone/ipod/ipad after you are finished, but within the 20 minutes- they can download anything without re-entering your password. Thats what they were saying on the news story. I had NO idea about that!
