on iPhone v4.5b46: while writing a comment on www.iphone-ticker.de and turning the device to landscape orientation, the bounds for the responsive website are not updated, see attached screenshot.
Greetings from Germany!
This is likely the limitation of the iOS's UIWebView APIs. If you try this in other apps that uses the same APIs like Chrome, the same thing happens there.
This will mean that Apple have to fix this in their code to allow the UIWebView to resize the site properly.
