Thread: Is there any way that Apple can tell an iPhone has been JailBroken?

  1. #1
    Default Is there any way that Apple can tell an iPhone has been JailBroken?
    Is there any way that Apple can tell an iPhone has been JailBroken if it's been restored (unJailbroken)? If I JB it and then later restore it.....is there ANY digital fingerprint left that Apple can see with some special diagnostic tool?

    I have spoken to lots of people and it seems 50% say that Apple can tell and the other 50% say no way.

    I'm really confused and would like a straight answer from someone who knows.

    No. A restore deletes EVERYTHING.

    If you do a full restore and set up as a new iPhone there is absolutely no way Apple can tell. Restores deletes the entire memory of the device and restores it back to factory setting. The iPhone would b back at the stage it was when your first open that sweet black/white box.

    Yes, they can. If the baseband has been tampered with at all (i.e downgraded on 2g, or stopped from upgrading on the 3g) Apple do have a simple diagnostic tool that can detect this, although they rarely use it.

    Yes the system leaves a log in the phone that is updated with the restore by itunes. Everything that goes on with the phone is stored in itunes logs and resynced upon reloading the FW.

    So your saying if I JB and then do a restore that "Everything that goes on with the phone is stored in itunes logs and resynced upon reloading the FW"

    Other people say the opposite. What do you base your thoughts on?

    I'm still so confused because there is just so much conflicting opinions.

    vone1 has the programme. ive seen screenshots and im sure he could provide pics if necessary. they can tell, but the main thing is they dont usually use this software. but if you get a **** genius then your in trouble. 9 times out of 10 you got nothing to worry about though.

    at the moment, my 3g iphone is on 2.2 but is still running 2.0 baseband. if i stock restore to 2.2, my baseband gets updated, but apple will still be able to tell that my baseband has been tampered with in the past. the same goes with the 2g etc etc.

    In a nutshell, your JB can be detected, yes.

    Nun ya. You asked a question and got an answer. If that isn't good enough, don't accept it.

    Be reasonable. I don't know you, I should just take your word as gospel? Are you a prima dona that can't be questioned on a statement that you made in a public forum? I have bought an expensive device and want to make an educated decision regarding jailbraking the device. If people don't or can't back up their statements, it's just more anecdotal evidence that can be put under the banner of urban myth.

    Thanks for the info. Can you tell me how it's detected?

    This information Will be good, as what your saying goes against what the majority of people say on other forums.

    It would be great once and for all for people to finally have the correct answer to this oft asked question, backed up with irrefutable proof.

    There are ALWAYS ways to tell on computers, everything leaves a digital fingerprint. Yes they can tell, but it is highly unlikely they will bother to go to the means to do so.

    If you want to see something REALLY interesting, look at 23:51:55.

    The new FW DL's updates to itself. What does this mean? Direct link to apple server.

    Wish that worked! It gets sent to Apple when you first connect to a valid Wifi spot.

    ^ Do you have some proof for this? As far as I know, Apple can't just take it, it needs your permission.

    more proof pls and maybe a screenshot of this so called program that can detect a former jailbroken phone.

    so what if your still on 2.0 firmware jailbroken with original 2.0 baseband and you revert back to original settings? I think they can only find out if they see that the baseband has been tampered with.
