Does not work with the KDXG. I still get "your browser does not fully support javascript" message, even with javascript enabled and in advanced mode. Not that it matters, I can tell by how it takes forever to load web pages and DL books from Amazon that the 3G via AT&T is nearly worthless in my area. I had the same problem with the Sony PRS900 3G, so it is definitely a problem with AT&T's infrastructure in my location rather than a problem with the 3G radios in the Sonys or Kindles.
