iOS 5 iFrame Scrolling Fix

I've read that iOS 5 has fixed the scrolling issues with iframes, but for the life of me I can't see to get it to work. I've added the CSS -webkit-overflow-scrolling: touch to the iframe and also have overflow:scrolling and I still can't scroll in the iframe, with one or two fingers. Has anyone been able to get this to work for them on a webpage? If anyone can provide a link to a working example, I would greatly appreciate it.

Thanks!
