Is there a jQuery plugin or JavaScript script that automagically loops through each CSS hover (found in an external stylesheet) and binds it with a double touchdown event?>
Try this:

... or check out the demo on my web site. Note that it's set up to only work its magic on the iPad - detecting all versions of the iOS is another question in my books ;)
It works on the basis of the fact that...
After you click a link on the iphone or ipad, it leaves a simulated mouse hover that triggers the a:hover css styling on that link. If the link has a javascript handler that keeps you on same page, the hover state will not change until you click on another link.
