Why does iOS 4.2 iPad update break this website layout?

I've been asked to fix a layout issue for http://www.ireland.com, which occurs on an iPad running iOS 4.2 only. The b开发者_如何学Pythonody content floats right and the header left, rather than all centred as they are on all other platforms and vendors.

Anyone aware of such issues or know how I might fix this?

I've only access to the iOS simulator on my macbook and can't get firebuglite working because it blocks copying bookmarklets. I wish I had some decent debug tools!

Thanks, Denis

ReadWriteWeb says that iOS 4.2 updates the browser with many new features. My only guess is that a new feature is reacting strangely with your CSS. Are you using a reset stylesheet on your website?
