Since there are more and more jailbreaks being created by hobbyists, each with their own respective quirks, you may have to change the behavior of your tweak / packaging depending on the jailbreak installed on the user's device.

None of this advice is foolproof but it's worth taking into consideration.

It's probably not worth supporting these. These jailbreaks are redundant and, arguably, harm the jailbreak community by merely existing.

If anything, you should have a warning letting users know something's wrong.
