Ask HN: How do you test mobile sites? Also, Kayak glitch.

A non-programmer friend of mine had me reproduce a bug he found in the Kayak Flight Search on his iPhone. If you go to kayak.com on the iPhone, tap Flight Search, select one-way, select two cities (I chose DEN and LAX), and click the drop-down button to show the calendar. The calendar doesn't show up! Worse, when you try to focus the text field the script code takes the focus away. So searching for flights is effectively broken.

I was reminded that testing mobile web apps is more difficult than testing regular web apps. I'm curious what fellow HNers are doing to test web apps on mobile devices. I'd also like to hear thoughts on how much mobile web testing will change in the near future and what projects will be behind it.
