    Exclamation f0recast says: "Jailbreakable: Yes" but "Untethered: Depends if it's Referbished"
    Hey guys, this guide:

    How to Jailbreak iPhone 3GS to 4.0 with PwnageTool | OS X

    says this:

    If you are on firmware 3.1.3 and jailbroken with Spirit you can not go directly to jailbroken 4.0. If your iPhone 3GS has the new bootrom you can not currently jailbreak 4.0. You can figure out what bootrom you have by running f0recast, if it says Tethered Yes then you can not currently jailbreak 4.0.
    So I ran f0recast and it doesn't say "Tethered Yes", it says:

    Serial #: ...
    Baseband: 05.13.04
    Bootloader: 6.4
    Model: MC135
    Jailbreakable: Yes (don't upgrade!)
    Unlockable: No
    Untethered: Depends if it's refurbished

    I'm guessing I can't jailbreak 4.0, but would love to hear otherwise! Look forward to finding out!

    Most likely you have a tethered iBoot. The only way to know for sure is to put your phone in Recovery mode. This is complicated, and should only be done by advance users.


    Download iFuntastic, and open it.

    Regardless of what version of iPhone OS you have, you can find the iBoot verson there under Utilities and Troubleshooting

    Use the following link to find out your iBoot version.

    Hard part is now getting it out of recovery mode.

    I have attached a precompiled copy of iRecovery.

    Open it with terminal and cd into the directory it was downloaded into.

    When in the folder type in: ./irecovery -a

    Your phone will reboot and no longer be in recovery mode.
