    I just jailbroke my iPhone 3G using PwnageTool 3.1. Since it is restored to the old factory settings, if I restore from backup (from before it was jailbroken) will my iPhone remain jailbroken after it restores? I just want to make sure.

    Don't understand what you are asking ?

    Are you asking if your JB phone has factory settings ? Like preferences ? That would be yes.

    The JB will happen if you use PT to create a custom restore IPSW, then you must use that IPSW in iTunes or the phone will not be JB. The use of a different IPSW will return the phone to a non-JB state.

    Yes. Restoring from backup only adds the data (music, apps, notes, etc) you had when you backed the phone up.


    You wont lose your jailbreak.

    Im pretty sure restoring from a non JB backup will KEEP your jailbreak. It would suck if you had to set up as a new phone EVERY time a new JB came out.

    Really think about what you're asking.

    Go jailbreak your iPhone/iPod touch, back it up, then restore it from that backup, and tell me if you still have your jailbreak.

    Why do you think most people avoid Apple's firmware updates other than unlocks?

    I think there's two different "restore from backup" people are talking about.

    One is when you restore the firmware by clicking the "restore" button, then iTunes reinstalls the firmware, and after that you get the option to "set up as new" or "restore from a backup." If you do this, you lose your jailbreak, as your jailbroken firmware was just overwritten by Apple's stock firmware.

    Then there's the "restore from backup" option you access by right-clicking on the iPhone icon in the left sidebar, and you get the pop-up menu that includes things like "sync," "transfer purchases," "backup," and "restore from backup." I'm pretty sure that this just loads your data and settings from the backup, but doesn't overwrite your firmware -- so you wouldn't lose your jailbreak if you do this.

    Why would there be TWO different "Restore from Backup"?

    Really think hard about what you're saying.

    Hey, I didn't write the program, Apple did. If you don't believe me, just open up iTunes, connect iPhone, and see for yourself.

    That's not what I meant.

    Why would "Restore from Backup" have 2 different functions?

    Um, it's the other way around -- there're two different functions, but they are both called "Restore from Backup."

    There is the straight up "restore" button and when you right click on your phone its "restore from backup."

    Night, you just mistyped in your original post.

    Oh, okay. But within this thread itself, I believe there was confusion between "Restore" + "Restore from backup," and just "Restore from backup" by itself. The OP asked if "restore from backup" would undo a jailbreak. Some people said no, some people said yes. But those who said it would undo a jailbreak were thinking of "Restore" + "Restore from backup," I believe.

    Sorry to steal the thread but i have a question.

    Heres what im going to do:

    Restore to 3.0
    Set up as new phone
    Updating using custom IPSW
    Set up as new phone
    Restore from backup

    Is that possible or will me setting the new phone up as 3.1 erase the backup?

    Once iTunes applies the IPSW, I believe the next screen is Set up as new phone or Restore from backup. You have to choose one or the other.

    Then, sync back your apps, address book, iCal, music, movies, etc

    Not sure why you are restoring to 3.0 first -- wouldn't restoring to a custom IPSW do the same thing, and save you several steps?

    Anyway, I'm pretty sure that iTunes creates a new backup every time you restore or update, but to guarantee you don't lose your backup, just copy the backup folder to somewhere else.

    So, now that we've established there are two different types of restore from backups, maybe we can get this OP back on-topic?

    From what I've read, the restore from backup that you click on in the left pane does just what a poster claimed above: it doesn't overwrite the firmware, but only restores the backed up data. So the question remains, will the iPhone remain JB when restoring from a backup in this way? Sounds like it will. However, if you do a restore+restore from backup, then it won't.
