You might recall that during CES I mentioned that Pandigital planned to start using an open firmware for all versions of the Novel ereader/tablet. I also mentioned that they had a retail box for the white Novel that showed a standard home screen (instead of the custom one they used before).
That open firmware is now available as a firmware update. Now that I have this firmware, I don't think it's worth the risk of hacking the white Novel. You can find and install apps just fine without voiding your warranty.
You can find out more about how to run the update process over on the Pandigital website.
