I read this. Which meant nothing to me. Kindle e-reader? Do all e-readers have the same OS?

Granted I may not be the target audience. Presumably some one looking to jailbreak their e-reader may have recognized this right off the bat. As someone who recently purchased a cheap kindle fire tablet, and was interested in the possibility of jail breaking, I was confused.

Edit: great post though! I researched previously in jail breaking kindle e-readers with not so much luck. Ever since I saw AWS use them as displays for snowball devices I started to see potential for other uses. Will have to try this out.

Since this targets vulnerability system, providing system version is more valuable than what model of kindle readers are vulnerable. Especially that Amazon either already patched this or surely will do it very soon.

Given that it said "every Kindle with a 5.6.5" I would assume that most likely it was every kindle at the time the exploit was written.

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.
