When I go to check for updates under Help. That option isn't provided on my itunes.

My Iphone doesn't seem to be sync or connecting to my PC any more and I'd like to fix that. One of the first things it suggests is to check for updates on itunes to make sure my itunes is up to date. It lists an option to check under Help for "Check for updates", which doesn't seem to be present when click on "Help".

Does that mean it's up to date?
