It does on the Touch. I use that as my main reading device, and have tested it. I only use kepubs on the Vox Kobo app.
I have the most locked down FB account in the world. No friends. No picture. No nothing. Set not to share anything to anybody. I have it because I have a very common name and all sorts of people with the same name believe that their gmail account is that name.
Nope, I am the only taming.noodles at gmail.com. (obviously not my real address). Every other day I was getting notices that indicated that some other Taming Noodles had set up an account in "our" name. I could get them pulled, but finally it seemed smarter to just set up an account.
I used to do FB a bit, but no more, don't trust 'em, don't need 'em. that could change, of course, but I doubt it at this point.
