I just got out my Kindle Keyboard (Kindle 3) and tried it out... the 3G still works! It's a bit slow, but you can launch the browser from the Experimental window, choose the Wikipedia bookmark, and it still loads. I was able to search for the entry for the above referenced book and read it.
(That said, it's probably the first time I've used my Kindle Keyboard in months. I mostly use my phone or Samsung tablet for reading Kindle now.)
