Not sure whose bug is it, but I am having trouble loading http://search.twitter.com/operators/ in UIWebView on iPhone. The problem is not specific to my app—you can see this bug also with the official UICatalog example.
The problem is specific to search.twitter.com/operators/ and UIWebView. The link loads fine in iPhone Safari, and http://search.twitter.com/ and other Twitter links load fine in UIWebView. But, to provide inline help for search, it would be handy to load this in UIWebView too. I didn't have time to investigate if the bug is on server or client side. My hunch is that Twitter may not handle the user-agent of UIWebView correctly, but this is just a random guess, would need to investigate more. rgds, Jaanus
