jQuery UI Tabs - ajax php

I have some really standard jQuery UI tabs that work fine on my Mac in Safari, Chrome and Firefox however the content doesn't load on the iPad / iPhone and I don't understand why, here's a link:

The first two tabs, Monday and Tuesday are here:

I would appreciate some help - thanks.

The Tab content shouldn't include any of the standard html tags such as: html, head and body.
