-webkit-overflow-scrolling:touch disables the feature where tapping the phone's status bar scrolls content back to the top. That has been a showstopper for most of the things I have worked on.
One workaround that was functional but subpar experience-wise:
Put a transparent UIView over the status bar and wire it up to call a javascript function on your UIWebView using stringByEvaluatingJavaScriptFromString.
