title_body: Does un-registering a kindle device remove ebooks downloaded to the device? I would like to know if I can still continue to read my ebooks downloaded to one of my kindle devices, even after unregistering the device from my amazon account?
  
  Can I un-register a kindle device (to test and wanted to know if its safe to do it) and re-register it again?
  
  Appreciate your advise!!
upvoted_answer: For an Kindle Fire, no, all purchased content will be removed when you de-register. For an e-ink Kindle, ebooks that have been downloaded will remain on the device until they are removed. Note, however, that this will not necessarily be the case forever.
