redsn0w Jailbreak For Firmware 3.1.2

dev teamYou now have another option to jailbreak your iPhone on firmware 3.1.2. redsn0w had finally been released. It has been in beta stage but is now complete. You can download it and read more at the Dev Team’s blog at This jailbreak is like blackra1n where you don’t have to restore your iPhone in order to jailbreak. PwnageTool creates a custom firmware you restore your iPhone with. redsn0w 0.9 comes with new features like changing the boot logo! You will lose any unlocks and if you have a new iPhone 3GS or iPod touch out of the box 3.1.2, it still a tethered jailbreak:

This version of redsn0w does not provide an untethered jailbreak for those of you with brand new iPhone 3GS, iPod touch 2G, or any iPod touch 3G. redsn0w will jailbreak those but it will still be a tethered jailbreak until some new exploit is found and released.

  1. I jailbroke my ipod touch soon after I first got it. But after the app store update was released, I restored and haven’t jailborake since. Is it still worth doing? I seem to remember that the battery performance dropped a lot after it was jailbroken, but maybe I had apps running in the background with it jailbroken.

    I did like the Cydia installer though.

  2. So, just to get this right… My wife just upgraded to a 3GS 2 days ago and if I understand correctly… I can use this to jailbreak her phone, but if she restarts it, then it will no longer be jailbroken? Then I just run redsn0w again to re-jailbreak it?

  3. Does it work of 3.1.3? Cause that was just released. Hurts without tethering.

  4. Josh Wiens says

    WOW!!! Finally. And…it doesn’t run on PowerPC based Macs…LAME!!! Do they have free Intel emulators somewhere?

  5. I take that back. Don’t know if it works or not, but a warning was issued to not upgrade.

  6. can someone,anyone pls tell me how to get my 3gs (currently running 3.0.1 baseband 4.26.08 jailbroken via previous redsn0w), updated to 3.1.2 with latest redsn0w keeping current baseband. ive tried updating via pwnage tool,no luck. and now when I run current redsn0w it says ‘unable to recognize specified ispw’ where can i retrieve the pwned version of 3.1.2, not a torrent so i can move foward with the latest redsn0w. HELP!! thanx in advance.

    • Just update to a regular 3.1.2 firmware version and then run redsn0w. You cannot use a jailbreaking tool (redsn0w, pwnage tool, blackra1n) to update your firmware. Updating the firmware must be done using iTunes. Go to the link below to find any firmware for any iDevice.

  7. Is there an Intel emulator out there that can run this on PowerPC architecture?

  8. Welcome to last year redsn0w.
    I bet it sucks that you just releasing a jailbreak only for Apple to update to a higher version.

    What sucks is that the Dev Team took this long to come up with this cleanly. It just goes to show you that one person can be smarter and quicker than a group.

    While the dev team does good, they are just too slow.

    Hopefully GeoHot will jump and update blackra1n to deal with 3.13

  10. l want cydia
