Layout breaks on iPhone and iPad in portrait mode

Hi, a site I’m building is breaking on the iPhone and iPad in portrait mode (is fine in landscape) and I can’t figure out which elements are doing the damage.

It’s too late for fluid design and other ways over building for mobile from the ground up, I need to figure out how to make it look decent on mobile.

Any suggestions?

You could just make a new stylesheet for the mobile platform using CSS3 media queries.
