I've just got my first iPad and am still exploring. I get my books from a variety of sources and use Calibre and a Sony 505 at the moment (none have DRM). I've got Stanza on the iPad but I'm having a teething problem. If I put an ePub book into Dropbox and open it on the iPad, Stanza says there's no suitable format to view. However, if I email the same book to myself and open it, it drops beautifully straight into Stanza.
Is this a Stanza problem or Dropbox?
