As far as converting from books downloaded to your e-reader, I saw mentions you need a pre-PW3 for DeDRM to work.
However when I checked the MobileRead wiki
Kindle paperwhite 2 says KFX support was added via software update. Does this mean the PW2 needs a certain firmware version or lower for DeDRM to work or that it has the earlier KFX that can still be converted? I did see
the post regarding firmware versions for the PW3 but I dont know if that also applies to the PW2 or if they share the same firmware.
For reference the
Kindle paperwhite 1 wiki page doesnt list KFX support at all.
I would assume in the event Amazon disables "Download and Transfer" for purchases that books downloaded directly to a PW1 could still be DeDRM'ed regardless of firmware?
