    Yes, you will have to restore the phone after you do that thus losing everything you have on it including jb and unlock.

    Thanks. I am selling it, and would like to erase as much as possible for security and privacy, but without having to do a restore and reunlocking and rejailbreaking it.

    Do I have another option to preserve the jailbreak and unlock and eliminate as much data as possible?

    It's not that hard to restore and rejailbreak/unlock. It can be done in less than 10 minutes, especially if you are not going to sync anything. Best practice when selling an iPhone is:

    1) Erase all Content and Settings
    2) Restore firmware
    3) Setup as new iPhone (do not restore from backup!)
    4) Jailbreak and unlock.
    5) Profit.

    Try redoing the restore.

    Erase is a really bad thing. Some have got past this by repeatedly trying a restore in DFU mode. Keep trying; it's all you can do. See my sig for assistance, if needed.

    I agree that "Erase All Content and Settings" is a bad idea, especially on a jailbroken phone. Something about the jailbreak modifications to iBoot makes it really hard to restore. When I sell, I intend to just restore to a custom 3.1.2 firmware and set up as new. Sure, someone with the equipment, knowledge, and motivation could probably recover data...but I doubt anyone would have the motivation to try.

    If you have been silly enough to use this option on an iphone 3G with 3.1.2, is there anyway to then restore or whatever back to 3.1.2 rather than 3.1.3 or is this the only optional available now?

    Thanks

    Just download a 3.1.2 FW and shift-restore through itunes
