Well, the forum explains clearly how it is done, but maybe not so evident for everyone how it works and I understand that is what you want to know.
The way it works: the Kindle is able to run programs from the main memory BUT only those programs that are digitally signed by Amazon. The kindle is able to check if the application is really made by Amazon. What you basically do in the jailbreak, is this: add an extra certificate to the Kindle, allowing the programs that are digitally signed by the designers who publish there programs on this forum to be accepted by the Kindle. This way you can get extra functionality to your Kindle. I hope is an answer to your question. |

Depends which jailbreak.
As NiLuJe pointed out, the Wiki has lots of information about how the Kindle works and what the jailbreak does. Our "Start Here" master index (the sticky one right in this subforum) contains links to Wiki indexes where most things eventually get consolidated. Failing that, you could open up the jailbreak and examine it -- you will notice that it is mostly bash scripts. Basic overview: It puts a MobileRead shared certificate for validating signed updates (you can create a corresponding update_*.bin using kindletool), it bundles in the MKK (MobileRead Kindlet Kit, formerly known as the Kindlet jailbreak) which contains a Test Kindle certificate for running non-Amazon kindlets, and it includes "gandalf", an entry point for quickly gaining a root shell. But of course, that is useless trivia, in order to do anything practical, which you no doubt want, you will have to ask a more pointed question, or trawl the excellent Wiki. |
