title_body: How to best read a PDF on Kindle?
upvoted_answer: The Kindle pdf app only works well with plain .pdf files, however, the user experience isn't that great, because the pdf app doesn't have a reflow option.
  
  If you haven't updated your firmware to the latest firmware version, you might be able to jailbreak your Kindle and to install KOReader, which has a much better PDF reader. BTW, you can also read epub2 books with KOReader, as long as they don't contain RTL text (e.g., Arabic books or Japanese Mangas).
