While looking to see if I could find some kind of emulator for mobile browsers I came across BrowserShots.org. This is a tool which allows you to select browser versions to test your website with. Once the test is done screen shots of the results are published on a web page that you can look at and then download all the screen shots. It takes a little while to run, but it seems to do what it advertises. Best of all, it’s a free service!
