An acquaintance is thinking about jailbreaking their iPhone. Not being an Apple user, I haven't followed the topic closely, but I thought this was generally believed to be a bad idea from a security perspective (at least for a primary device).
Unfortunately what I can easily find online are people with no obvious credentials saying it's fine and security companies (who often overblow risks, like the infamous "juicejacking") saying it's bad. I'm hoping the Fediverse might be able to give me a more nuanced or fact-based perspective.
