Description Wei Lou 2012-03-22 00:58:57 PDT 
Run codes below on iOS 5.1's Safari:

<!DOCTYPE html>
<meta charset="utf-8">
<title>An HTML5 Document</title>
<style>
	div:nth-child(1) {
		background: yellow;
		width: 400px;
		height: 300px;
	}
	div:nth-child(2) {
		background: red;
		width: 400px;
		height: 300px;
		overflow-y: auto;
		-webkit-overflow-scrolling: touch; /* Can't be run! Bug! */
	}
</style>
<div>
	Click me!
</div>
<div>
	Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!<br>Scroll down me!
</div>
<div>
	So you can click on the first div element. It's OK. But you can't scroll down the 2nd div's contents via touch move on iOS 5.1's Safari. This is a bug.
</div>
<script>
	document.addEventListener('click', function (event) {
		event.preventDefault();
	}, false);
	document.querySelector('div:nth-child(1)').addEventListener('click', function () {
		alert('Clicked successfully!');
	}, false);

	document.addEventListener('touchmove', function (event) {
		event.preventDefault();
	}, false);
</script>

Please file this bug via <http://bugreport.apple.com>. Most iOS specific bugs go there.

I won't report any bugs to Apple anymore. Apple product's UX is so terrible. Your WebKit bug report system and Apple bug report system ate both garbages.
