Correct. At the time, this worked on the Paperwhite 2, 3, Voyage, and Touch. Forgot which version of the touch, they update that one a lot. I'll try to clarify

Correct. At the time, this worked on the Paperwhite 2, 3, Voyage, and Touch. Forgot which version of the touch, they update that one a lot. I'll try to clarify that a bit better when I get some time. While this exploit is obviously closed, Kindles can still be jailbroken via a new method. See the mobileread forums.
