Are you sure that you have it working over 3G? I just tried this using my Kindle Keyboard 3G and my document wouldn't download until I reconnected to my wifi (I had set my Kindle to forget my network before I started). I have Whispernet delivery enabled in my account settings but my charge limit is set to $0.00.
