If there are any problems, it's because you're using an old browser. (As far as I know.) The iPhone browser definitely counts as "old". ^_^

In particular, a bunch of browsers don't support specifying background-size in the background shorthand yet. It's in modern WebKit, but that hasn't trickled down to mobile versions yet.

Yup my 4S sure feels old. Sure wish I had a modern browser like IE9 on there. Blast!!
