Is it possible to change the JavaScript alert title in a UIWebview in iPhone?

Basically you cannot change the title, but recently I have found a way to show an alert dialog with no title.

var iframe = document.createElement("IFRAME");
iframe.setAttribute("src", 'data:text/plain,');
document.documentElement.appendChild(iframe);
window.frames[0].window.alert('hello');
iframe.parentNode.removeChild(iframe);
