    There is a complete Erase & Reset on the iPhone 4. If I do that it will bring the phone back to factory settings and must sync to iTunes to activate. Can Apple Genius tell that it was jailbroken before?

    They will ask you a simple question, "Has this phone ever been jailbroken?" They will then stare into your soul and, as you urinate and defecate all over yourself, you will scream, "Yes, yes it was!" as you run screaming out of the store with your pants around your ankles, knocking several mall walkers into the pretzel/ear ring stand.

    All you have to do is restore the phone to stock firmware in iTunes.

    No, make sure you setup as new and don't restore from backup.

    If they have read the iPhone forensics book, yeah they can tell.

    In the normal 15 minutes, do they have enough time to diagnose, enter the info, and then dissect the erased files on the iPhone, NO.

    Since this would also mean hunting through the data and deleted stuff on the iPhone, you'd have a very good case of invasion of privacy against them.

    just curious on this one

    i jailbroke using spirit

    and when i wanted to try the dev teams restore ipsw to jailbreak 4.0

    it saidthis device has been previously jailbroken using spirit

    now if that can detect that after a fullreset and restore
    then whats not to say apple have something similar or am i thinking way outside the box on this

    What?
    What gave you that message and when?
    When you restore everything is put back to stock firmware. Don't restore from backup cause some jb stuff might carry over.

    There's no 'might' about it. :D

    I had a jb 3G and when I got my iPhone4 I restored from the 3G backup. When I jb'd on Sunday and installed MyWi 4 all my settings from MyWi 3 were still there.

    P.S.
    Please forgive my use of capitalization, punctuation and complete sentences. :)

    when 4.0 was released for iphone 3gs users
    i was one of those people who clicked upgrade straight away.
    after doing so i then went on my quest for a jailbreak.

    i then came across the dev teams way of doing it
    which was download the FW 4.0 from apple and create a custom restore ipsw
    using pwnage .

    so i went on my to create the restore ipsw following the dev teams tutorial
    after it done some checks of the FW it came back saying in red writing in pwnage tool
    that this device has been previously jailbroken using spirit- or something similar to this.

    I never heard of this before.
    So you were on stock 4.0 and tried to create a custom ipsw with pwnage right. But it obviously wouldn't work cause you had to be jb on 3.1.2 or below and on old bootrom in order to update to custom 4.0
    So pwnage gave you a generic error that you can't cause maybe u were jb with spirit or not jb at all before you tried it.

    Again?
    I don't see how some try to make a big deal or even bring up someones typos.
    If it's really bad thruout and not readable yes but some are way too anal IMO :)

    i had done a update to 4.0 iwas on 3.1.3 and jailbroken usin spirit
    after i updated i then restored to 4.0 and set up as new phone

    i then put the FW 4.0 Through pwnage and got that error
    i followed the tutorial every word

    to be honest i tried it about 10 times as i could not get my head round it

    so after a long period of exhausting all solutions i downgraded
    which in turn was just as bad to a novice who has never downgraded
    before
    as you are already aware i was naive about the whole shsh thing
    hence my apologie's

    totally agree
    as i said to him if it is understandable then whats the point in picking out silly errors
    it does not prove anything other than he is an uptight undividual that needs to get some IMO

    I see. I wonder if it was a generic error letting you know your device wasn't compatible in that state to use a custom ipsw made with pwnage.
    I don't think it actually detected you used spirit a few restores prior though.

    thats why i was curious when i put that out there

    if it was a generic error then it would surely just say failed to create ipsw
    or the ipsw is not a valid file please browse for an up to date one????:confused:

    edit: i really need to sort this laptop it keeps cutting out letters when i type them
    better sort it quick or that spell bee ploice will give me a ticket

    It all depends on whether or not you restored to stock firmware and set up as a new phone. If you have restored to stock firmware and set it up as a new phone it's essentially that, a brand new phone (hardware withstanding obviously). But if you go to stock firmware and restore as a backup, chances are some JB stuff will carry over and we can tell, and there is still a good chance they wont care as long as cydia isn't there anymore, unless you get a real d****e bag for a genius. But to be safe, restore to stock firmware and set up as new phone, simple as that.

    I believe you need to DFU restore and set up as new to completely remove all remnants of jailbreak. There are some jailbreak apps/settings that remain even after "normal" restore.

    I just brought my previously jailbroken phone in on monday because the screen died. I did a DFU restore as a new phone (not from backup) in hope that that would fix the screen (it didn't). When I brought it in the guy ran it through some diagnostics and showed me the results: there was absolutely zero info on the diagnostic since I had just DFU restored.

    Not sure if the DFU is necessary, but I can say with confidence that DFU restoring a phone as new will completely remove your jailbreak to the point that the genius bar won't be able to tell you ever jailbroke it.
