that seems to be the case but why should amazon go one step backwards.
if this is really working on 5.3.9 (PW 2013) than it might be worth downgrading,
Can anybody confirm that it is working on 5.3.9?
acc to the link:
"UPDATE: this feature is not just available on the new Kindle Paperwhite, it even works on the original Paperwhite, due to the Firmware update."
strange!
