@ixtab: You mentioned that the rescue pack does not survive, but in first post it still says for 5.3.3:
The jailbreak will survive the update.
Which is not incorrect, but maybe a little misleading. There should be mentioning that part of the components to get wiped (e.g. the rescue pack). And is it possible to include a bin package to install the wiped components? That might be pertaining 5.3.2 and 5.3.3. If they already got a seperate package, maybe simply link to it?
oh I see, that they are linked already, my bad. But would be nice to know which ones exactly need to be reinstalled.
