Yeah, you really need to use the browser's developer tools to have any 
chance when working with JavaScript.

Actually, just a couple of weeks ago I found Firebug Lite. It's like 
Firebug but it's a booklet in pure JavaScript (ironically). That means 
you can use it in any browser, include IE6 (yes it works in IE6), iOS 
and other browsers missing developer tools.

I have also used remote debugging when I debugged a site in the iPhone 
simulator. It uses web sockets (I think) to send the data to another 
browser where the actual developer tools are.
