HOWTO: Browser Testing for Mobile Web Applications by Mike Brittain
From the site:
Developers working on mobile web apps need to be able to test their apps or sites in all of the major mobile platforms. Unfortunately, there are not a lot of good resources online for how to go about this. You could pay for a service from a mobile testing company, like DeviceAnywhere, who provides access to a wide selection of real devices (using a virtual client). Or you could go the free route by installing a variety of SDKs and mobile phone simulators.
