The Dev Team just released RedSn0w 0.9.7b4, the latest version of their untethered jailbreak, which let me remind you, is still in beta. This updated version of RedSn0w brings the untethered jailbreak to your iPhone 4, iPad, and iPod Touch 4G for those of you on iOS 4.2.1.

The major improvement in this update is that you no longer need to run usbmux, which was very confusing for many of you (oh yeah, me included)…

Update #4: The fourth beta is now available (testers ONLY please!). Starting with this version, redsn0w no longer requires you to install and run a separate program for the usbmux (this was a non-trivial procedure for many).   It’s okay to keep that program running if you normally use it for ssh anyway.  We also think we’ve fixed a race condition in the GUI that was causing redsn0w to crash during the “Preparing JB Monte Files” step. Nothing at all has changed on the iPhone side (where the main issues are still just Bluetooth and Skype).

If everything goes well with this new update, the Dev Team will open up the beta testings to Windows users as well. Bluetooth and Skype are still a no go, but that should be a thing of the past soon.

You can download this latest version of RedSn0w from our iPhone downloads section, and check out our tutorial if you feel adventurous enough to try it on. Remember, it’s still beta!

    Looks like we wont see a release before New Years, although everything is possible =)

    HAHAHAHAHA! No thanks. I finally got around to updating my old 4.0 3G to 4.1 to erase all the old stuff and have a clean, slightly newer, slate, but I had to restore and jailbreak it twice and the third time barely worked. I’d open Cydia, upgrade all the essentials and stuff like always when you first jailbreak, and it would go into a constant restart, freeze a lock screen for five minutes, restart, cycle. Working now and I’m glad, but I don’t think I wanna try 4.2.1 on either my 3G or my 4 yet.

  • Almost … Just a little longer till we get the official public release

    hey hi… …i have a serious problem …i am running iphone 3g and i has sash save form 4.0 …and now i am also running 4.0 i unlocked it before ..but for a reason i update it with the latest firmware which is 4.2 and then when i am done i restore it with tiny umbrella and down it to 4.0 again.. and after that i jailbreak it with jailbreakme.com and unlock it with ultrasnow 1.2
    and after that in my network is showing searching all the time …my phone is locked to fido ..it doesnt’ even run with fido after unlocked….and when i remove/uninstall ultrasn0w it can run with fido …i don’t understand what wrong …i am doing the same thing what i did last time to unlock it ..

    will u please help me ..what’s happening right now..
    why it’s not taking any sim after unlock ..and why is’t not taking it’s own carier sim…

    • Tyler

      I believe that by updating to 4.2 you’ve updated your baseband which may or may not be downgradeable depending on your bootloader. Simply downgrading your firmware, you ARE NOT downgrading your baseband. You are now running a baseband not supported by ultrsn0w. So you either have to look into using the iPad baseband option available in redsn0w 0.9.6 beta 6. Or you may be able to use Fuzzyband (found in Cydia) to downgrade your baseband.

      Hope that’s of some help.

  • Koppis

    @Demon, try restoring and rejailbreaking, and if that doesn’t work try downgrading to 3.1.3

  • Jk

    @Demon try turning the airplane mode switch on/off a couple times. Also try resetting all the network settings to default via the settings—>general

    thanks!!!!

      Redsnow is a free product from the Devteam and it’s used to jailbreak most iDevices. I would not recommends jailbreaking 4.2.1 just yet because it’s still in a beta, unless you’re very wise when it comes to jailbreaking. If for some strange reason you do decide to jailbreak 4.2.1, the best option is going to their blog (I’m sure it’s linked in the article) and reading all you can about it. Also, YouTube is a good place for tutorials.

  • iheartmyipodtouch

    also…what does untethered mean???

    thanks 😛

    • Thomas

      Tethered means that when your iPod/iPad/iPhone turns off, it must be plugged into a computer in order for it to reboot; untethered means it boots as usually.

  • dave

    If i am jailbroken with .9.6b4, can I just run this and keep all my files on my iphone?

  • ToeJo

    It worked great for me. Everything seems to work except Bluetooth…which was expected.

  • Just wanted to say that you guys rock! Been following these developments (and iPhone download blog in general) and it’s become a nice addition to the daily daily. Happy New Year !

  • Boal

  • tij303

    Hi I have had a play with 0.9.6 beta 6 and it wasnt too bad but got my 3gs in a pickle and have just done a restore. My question is 0.9.7 beta 4 likely to be more stable and generally how long does it take for the ‘final’ version to come out ? Dont want the same faff as last time with most stuff not working
