The Kindle 3.3 Firmware has now landed…. not sure what happened to 3.2 unless it was internal and with the release of the new non-keyboard Kindle this has jumped to put them both at the same point I don’t know. Also worth noting that the “branding” is now “Kindle” and “Kindle Keyboard”: ostensibly the same hardware otherwise.
Featurewise there is nothing to write home about….. backing up to the Kindle account of your own documents as well as those from the Kindle store. All part of the cloud based service that the Kindle Fire (aka tablet) is aiming to tap in to. So it makes sense and shifts people in that direction. Not sure if anything else has changed…..
