I took at look at the changes present in the new Kindle firmware version 5.15.1.1 that is in the process of being released.
I found something that may be of concern to those with a jailbroken device, but I do know have enough knowledge of how the jailbreak works to know if it will be an issue or not.
The files pubprodkey01.pem and pubprodkey02.pem have been moved from /etc/uks to a new archive named etc/uks.sqsh.
Perhaps someone with more knowledge of the jailbreak could comment as to whether or not this is a problem.
