I've updated the
JB hotfix, which *should* restore the JB on 5.6.1.1 (for previously jailbroken devices). One potential caveat is that this might depend on the presence of a not-completely-ancient JB *before* the update. Can't remember the history right now, I just remember that this was never an issue for the PW2, but it might be for a PW1 if it was originally jailbroken ages ago.
Reinstalling everything *from the
snapshots* should do the trick, provided the JB can be saved.
(Completely untested, no time).
