A bit off topic, but worth a shot: I'm working on a rather simple web-based game and I'm struggling with how to test it for iOS/Safari/Webkit without having to go out and buy an Apple device?
You can rent virtual/remote iOS devices. Those are the only realistic alternative I know of and you'll probably need to expose your dev server to the internet somehow for it to work.
There are also open source webkit builds like GNOME Web (though they're quite different from Safari in many ways).
