    I'm trying to Jailbreak the iPhone 3GS with 3.1.3 Firmware using redsn0w but each time I point it to the 3.1.3 Firmware File it says Unable to recognize specified ISPW. I've tried redsn0w 0.9.2 and 0.9.4. Neither of them work. What's going on?

    All may not be lost contrary to the doomsayers above. Try using sn0wbreeze instead of redsn0w. If you need to unlock your phone though you are well and truly out of luck but for a jailbreak you can give it a go.

    Please

    do not use this advice and use Sn0wbreeze. it's not a good jailbreak tool and has caused lots of problems for those that have used it. wait for a real jb tool from Dev-team or Geohotz probably a month or two.. ;)

    Will only work if the phone is "pwned" to begin with. There are no options for him at this moment, but to wait (possibly until the public release of 4.0).

    That's also false.
    Nothing can jb a 3GS on 3.1.3 at the moment.
    And if he wasn't jb before he prob don't have his shsh's saved in order to downgrade.
    So in short nothing for now.

    Um, some iPhone 3GSs can be jailbroken if they're at 3.1.3. I've done it on mine. Don't they just have to have the old bootrom?

    Yes but you must go from 3.1.2 to the jail broke 3.1.3

    You can not go from 3.1.3 to 3.1.3jb as the bottom is updated at that point.

    Only if you had your SHSH's saved so you can downgrade to 3.1.2
    Or be JB with the old bootrom on 3.1.2 and update it to custom 3.1.3

    1) It is not possible to jailbreak a 3GS iPhone of any kind at 3.1.3 with currently available tools.

    2) If you have saved your 3.1.2 SHSH saved (either locally or through Cydia), you can downgrade your phone to 3.1.2 and jailbreak using redsn0w, blackra1n, or (if you have the old bootrom) PwnageTool.

    3) /end thread
