How to make iTunes not automatically open when connecting iPhone?

Hey everyone! I have the latest iTunes and the latest update for my 4S. I don't want itunes to open up when I connect my iPhone in since it's very annoying. I've been looking everywhere online and in itunes and I can't find a single thing. I look through edit - preferences, nothing is there. I go to devices, nothing. I go to my actual iPhone summary on iTunes and there is no option there. Thanks for any help!!


Edit > Preferences > Devices > Prevent iPod, iPhones, and iPads from syncing automatically.
