I wonder if this will undo a jailbreak? I mainly use CoolReader to read ePub books on my trusty Kindle Keyboard, because of its better kerning and hyphenation.

  Generally jailbreaks can be saved across kindle updates, but you should update to the latest version of the jailbreak and hotfix first. Some extensions might require reinstalling. Of course, if you have an old device, it's probably jail breakable even on the newest supported version. Latest jailbreak is for 5.6.5, and it's been confirmed that you can update to the latest version after jailbreaking and keep it.

    Thanks for that info. It's been so long since I've done the jailbreak that I barely remember the process.

      Ask on mobileread, the devs are super friendly.
