Aside from the other apps that can read the file (try Stanza), check to see if the book is available on Amazon. If it's a PD book you'll likely find it for free and formatted to work with Kindle app. It is a "Kindle" app after all.
Edit: Try sending it to your iPhone. "firstname.lastname@example.org". I will be converted into a Kindle book.
Edit2: The "@kindle.com" email option is not available for iphones or ipods.
