Say, I purchased an iPhone (not from Apple or any official reseller.)

How do I know that it's not Jailbroken?

PS. My concern is the presence of key loggers or other tracking software.

  • Just restore it with iTunes when you get it, and you'll be good. – Andrew Larsson Apr 27 '16 at 3:23
  • @AndrewLarsson: That "answer" that you linked to doesn't actually have an answer. – c00000fd Apr 27 '16 at 4:15
  • Yes, I know, but this question is still a duplicate of that question, and duplicates are linked/merged so that when someone does answer the question, they don't have to answer it in 6 different places. – Andrew Larsson Apr 27 '16 at 4:36
  • So far this entire discussion is really missing the point entirely. If you just got a 'new' phone the first thing to do is wipe it & start afresh. Until you do, nothing on it belongs to you; you can't even tell if it's activation locked. Once you've nuke & paved it, it cannot be jailbroken any more, even if it was in the first place. – Tetsujin Apr 27 '16 at 6:27

    Then, I'm afraid there's no way round that. You won't have iTunes, you don't trust the phone. Throw it away. – Tetsujin Apr 27 '16 at 6:36

Not being familiar with jailbroken phones I can't offer a "what to look for" hint but really all you have to do is hook it up to iTunes and reinstall the latest OS update.

  • Thanks. That's something. Unfortunately I don't use iTunes. It's an awful software (especially on Windows.) So I'm not really looking forward to installing it again. Instead I was hoping for some official Apple app that I can download to test it? – c00000fd Apr 27 '16 at 0:28

The best way is to go into Settings>General>About and scroll down until you see Serial Number. Apple has a verification website Here to determine if the iPhone you bought is authentic. All you have to do is enter your Serial Number. If it comes back with

"We're sorry, but this serial number is not valid."

Then your phone is non-authentic and fake.


Try looking for the app named Cydia, you can use Spotlight to search for it. It is a standard app that's installed once iOS has been jailbroken and it cannot be deleted nor uninstalled.
