I had to modify the code slightly, but it works fine on my IPhone.
<!DOCTYPE html>
<title>Will it kill the iPhone?</title>
<body>
<p><input type=text id=box>
<div id=label>Test</div>
<script>
var box = document.getElementById("box");
var label = document.getElementById("label");
box.onkeyup = function() {
label.innerHTML = box.value;
};
</script>
I also tried setting a timeout to mimic the DeferredCommand I was
using:
setTimeout('label.innerHTML = box.value',250);
Can't get the pure JS to crash the IPhone. Seems to me that it is a
GWT issue...

Tried using FlowPanels. Didn't seem to make a difference
