@rsm: Okay, Yifan's version is a tiny bit deprecated now that I got mine to get a bit smarter, but it *should* theoretically work, although I don't recall if it someone actually ever relied on it on FW 2.x, because it's way, way overkill there, and I'm not quite sure the behavior is sound there. (Been a while since I worked on 2.x, feel free to correct me, but that particular bit of Yifan's stuff was primarily aimed at 3.1 & 3.2).

What I can tell you is that you will not, ever, be able to install one jailbreak on top of the other: to avoid utter breakage, both installers are smart enough to detect each other and abort (I don't recall which error code each triggers on that particular FW version though, but it should be made clear in the logs anyway [enter ;dm in the searchbar]).

Another thing I remember is that Yifan's uninstaller is slightly broken, in that you actually need to *restart* (as in reboot, not a reset to factory default, or a simple 'go to sleep/wakeup' cycle) to actually get the device back in a sane state.

Note that the reverse *might* also be true: you may need to restart the device after the install process to actually 'enable' the JailBreak.

Also, due to the nature of how those JB iterations work, handling the uninstall of *both* version of the JB in one single package wasn't a sound decision [and was possibly technically impossible at one point]). So you *need* to use the uninstaller of the very JailBreak you used.

And no: using an older version of anything Kindle related in that context (ie. custom stuff) is *never* a good idea, and often a very, very bad one.
