The Windows jailbreak tool, Sn0wbreeze, was recently updated to perform a tethered jailbreak on iOS 4.3.1. We told you about the newest beta release a couple days ago, and many of you have successfully been able to jailbreak your iPhone on 4.3.1.

The biggest downer with the current Sn0wbreeze beta is that it’s a tethered jailbreak, and we’ve recommended holding off on iOS 4.3.1 until an untethered solution is released from the Dev Team.

To our surprise, an iDB reader sent us a video of his iPhone 3GS running an untethered jailbreak after using the latest Sn0wbreeze 2.4b1…

Reader Ryan was experiencing some issues with upgrading his 3GS to 4.3.1,

“Don’t quote me, but mine is. I don’t know how, or why. I had to restore it really weird, because my Power button is broken, and I had to restore to a custom, hacked 3.1.3 firmware to cause it to enter DFU Mode. Then, I used that DFU Mode to restore to my cooked Sn0wbreeze 4.3.1 firmware. So, when I installed WinterBoard, and my phone restarted, I expected to have to do some cooky thing to make Cydia work, but… it just worked. I can make a video if I must.”

The video he ended up making demonstrates his 3GS running Cydia 1.1, untethered, after jailbreaking with the Sn0wbreeze 2.4b1.

While we can’t affirm the legitimacy of Ryan’s situation, his video does seem to show what he claims. Does this mean that there are other cases of random untethered jailbreaks from the Sn0wbreeze beta?

What do you think about Ryan’s discovery? Better yet, let us know if you’ve experienced something similar after using the latest version of Sn0wbreeze to jailbreak iOS 4.3.1.

    I don’t like snowbreeze but I just might give this ago…

  • Max

    What the fuck
    Random untethered???
    That’s not even possible

  • Marsavis

    I luv sn0wbreeze cuz its the only way to preserver your baseband on an I4.

    • alf15

      Tinyumbrella also does it and is very easy to use 😉

    • AnotherBrian

      No it’s not, I’m on 1.59 with 4.2.1 jailbreak. And I have never used snowbreeze, tethered sucks as far as I’m concerned. I can wait for something that’s done right.

  • old bootroom, obviously untethered

    • Burge

      On the video you can see it’s a MC model ..new bootrom

      • Anonymous

        BTW, I have an MC iPhone 3GS and its old bootrom, all the 3GS’s where MC models.

      • Burge

        Your right about MC model my mistake , it been awhile since I’ve think about new/old bootrom, it’s something to do with the last 2 digits in the serial No ..week 47/48 new bootrom..i think.. but 28 is old bootrom

      • Anonymous

        Yeah correct, the 3rd and 4th digit is the week. Anything past 48 is new bootrom.

    • Anonymous

      The old bootrom weren’t untethered by Sn0wBreeze anyway.

      • Burge

        Serial No 84928 ..it’s a old bootrom..that might help with his untether

  • Bill

    I have a MC model 3gs. According to the serial number, it is a model that comes with the new bootrom. Except when i check, iboot reports the old bootrom. I think it is because my phone was a reman when I bought it. Cleaned it up and gave it a new serial number, never replaced the hardware. That could be the same thing here. I’ll have to give snowbreeze a try.

  • Patrick Nilsson

    Same thing happened to me, exept it wasn’t snowbreeze. And this was a while ago when I really didn’t know much about jb. I was jailbreaking my brothers new bootrom 3GS iOS 3.1.3 with blackrain, which was tethered. everything went as I planned it to go. Then I installed something from Cydia that required a reboot. And it just rebooted without any problems. And i tried several times and the phone did all the work. Awesome though

    • c0ntr0l

      3.1.3 was sprit jb not blackra1n

  • QSLADE

    I CAN SAY IT WORKS LIKE A CHARM. I HAVE A 3GS AND I HAVE BEEN TRING TO JB THIS THING SENCE THE RELEASE OF 4.3. AS FAR AS HOW I CHOSE OLD BOOTROM INSTED OF THE NEW AND WELL IAM JBKEN GIVE IT A TRY

  • fghfjk

    Sn0wbreeze 4.3 Beta is not tethered its semitethered.

    • Pete

      What does semi-tethered mean? I understand tethered and untethered (however stupid these terms are), but semi? Cheers Pete

  • Bada

    Its not random. The morning i saw the jailbreak i just had to update because 4.2.1 greenpoison was doing my nut in (long story). Anyway, back to the point. Basically if your iphone 3gs has the old boot rom, then snowbreeze will be an untethered jailbreak for your phone. Ive also noticed a massive improvement in battery life and overall performance of most cydia apps and etc.

    • Robson

      Same here, I’m running 4.3 on 3GS old boot rom and I only plugged my phone once to my computer to Sn0wbreeeze it, haven’t had to plug it in once after jb

  • its a fake…look back on the video hes always video taping the iphone but he never shows the part where tue usb connector goes…so he probally had the iphone connected to the computer thats why it turbed back on

  • For the record, when I saw his serial number, I wrote it down (84928UK93NP) and checked Apple’s support site. The serial number is legit because it says active and expires July 21st of 2011. Just saying that this could actually be legit (but I’m still skeptical, all the same).

  • i think its fake for he necer shows the entire ipod he only shows from tye home button up n never shows the usb connector

  • szdifjcnkvfj

    Two things:
    1)You can easily fake your firmware version
    2)This guy doesn’t have 4.3.1 SHSH on Cydia, but I don’t think Cydia saves 4.3.1 so take that out.

    • Good point. I forgot about that for a second. How do I take a comment down because now it doesn’t make sense to me.

  • George W. Bush

    maybe they uploaded the icorect version of SB JB

  • Tbv

    It is a 3GS made on the 28th week of 2009, so it is an old bootrom. Snowbreeze 2.4.1 is untethered for old bootrom 3GS. It is tethered for 3GS with new bootrom and iPhone 4 on IOS 4.3.1.

  • Bada

    Again i can confirm, mine is untethered. I have an iphone 3gs old boot rom

  • x8

    snowbreeze 2.4b1 don’t support custom bootimages, rigth?so why didn’t boot with the apple logo on this video?…

  • Eric

    Old bootroms are untethered for life, this is not news. Besides, the video could easily be fake, he never shows the connector during the reboot, he could have it plugged in for all we know. Dumb post.

    • Clark

      Yes, iPhone 4 16GB was tether JB successfully and after reboot with iBooty, iPhone 4 would shut off unexpectedly. Rebooted over and over. But iPhone came up with error on iTunes. Phone had fried internally proven by error code.. 1602.. I think. Can’t really remember. Apple sent me a new one though. I’m waitin for an untethered now for sure.

    • … I think it was error 1602. Apple said some of my internal hardware had been fried and they gave me a new iPhone 4. Definitely waiting for untethered JB now.

  • Slympickens82

    I can confirm, old bottom iPhone 3GS will do untethered jailbreak using snowbreeze custom ipsw.

  • Dave

    This has just happened on my iPhone 4. Planned on trying the tethered jailbreak but when I restarted phone it booted fully back up.

  • Dave

    Though just tried Cydia and it just crashes.

  • ramos96

    ok i built the custom ipsw with sn0wbreeze and could never get it to boot to DFU mode :/

  • valenteno

  • Chan

    OLD BOOTROM IS OF COURSE “untethered”

  • My iPhone 3gs is also untethered. this is real!

  • @dave i have an iphone 4 and when you retore with custom firmware you are correct it is untethered kind of basicly it has cydia but that crashes like you said so you have to use ibooys then it becomes tethered and cydia doesnt crash (i dont think it matters what bottrom you have on an iphone 4)

  • roberge
