Blank screen with apple-mobile-web-app-capable and Facebook Connect

We've got a few pages that use the apple-mobile-web-app-capable meta tag (value="yes"), but on a login page that allows Facebook Connect, you get a blank page when you clic开发者_开发问答k on the connect button. I've seen this posted on the old FB developer forums, but with no relevant responses. Has anyone figured this out already?

This could be a bug in facebooks API. I don't think they've tested their API in iPhone web app mode. Issue can be followed here: https://developers.facebook.com/bugs/317323871621290

The issue have been raised here on Stack Overflow a couple of times too: How do I get back to the iPhone web app after having logged in with Facebook Connect?

blank white screen after FB login via web app?
