Sn0wbreeze To Jailbreak iOS 4 For iPhone 3GS (New Bootrom) Coming Soon

iPhone 4 - First Impressions

iPhone jailbreaking community has released tools like PwnageTool, Redsn0w and Sn0wbreeze to jailbreak iOS 4 for iPhone 3G and iPhone 3GS users. But in case of iPhone 3GS, they only work if you’ve an iPhone 3GS with older bootrom, which essentially means that users who bought their iPhone 3GS after mid-October last year are out of luck.

This might soon change if you go by a new video, which shows iPhone 3GS (with new bootrom) on iOS 4 that’s jailbroken.

AKinGdom1 who has published the video claims:

As of today, Im one of only a handful of regular jailbreakers to be be pwned on 4.0 with a new bootrom 3Gs. That could always change tomorrow, who knows.

The only chance of being able to use a simliar tool to is to have 3.1.2 shsh blobs saved.

iH8sn0w, developer of Sn0wbreeze has confirmed that the video is indeed real:

The cool video here — // Is indeed real, but requires the 3.1.2 SHSH blobs.

and Please don’t ask for a release on this. I’m not planning on it.

Alright… If anyone has their 3.1.2 SHSH blobs, NOT 3.1.3. Then I’ll see if I can produce a tool that will do this job…

So it means that:

  1. It will be a tethered jailbreak, which means that the jailbreak needs to be reapplied every time you power down your iPhone 3GS. If you let the battery run out or restart your iPhone 3GS then you will need to reapply the jailbreak by connecting to your computer (tethering).

  2. It will only work if you had saved your iPhone 3GS’s SHSH blobs (or ECID files) for iPhone OS 3.1.2. It looks like it won’t work with iPhone OS 3.1.3.

  3. It should probably also work for iPod Touch 2G (MC models) and iPod Touch 3G.

You can use F0recast to find out if your iPhone 3GS has newer or older bootrom.

Comex, developer of popular jailbreaking tool, Spirit jailbreak for iPhone OS 3.1.3, iPhone OS 3.1.2 has discovered another userland jailbreak in iOS 4 similar to the one used in Spirit jailbreak that has helped in jailbreaking iPhone 4. It might help also in jailbreaking iPhone 3GS with new bootrom without the need to tether it.

If you have an iPhone 3G, iPhone 3GS (with older bootrom) and iPod Touch (non-MC model) then you can use our step-by-step tutorials to jailbreak your iDevices on iOS 4.

As always, we’ll let you know as soon as there are any further updates so stay tuned here at iPhone Hacks or follow us on Twitter or subscribe to our RSS feed.


iH8sn0w has published a step-by-step guide for now as he has realized it would take too long to develop the tool. You can checkout the step-by-step guide to jailbreak iOS 4 for iPhone 3GS (new bootrom) users with SHSH blobs (ECID files) here.

    I'll be FIRST to say… I'd rather wait for comix to work his magic with a new spirit jailbreak 😉

  • Yo Mama

    umm… Comex even 😛

  • AP

    Dont wait for Sn0wbreeze .. use this guide..

    It take a bit long but the results are 100%.

    Go back to 3.1.3 Jailbreak it and then use the method to patch and pwnd your iphone.

    It work for me, I am on 4.0 Jailbreak (3GS with new bootroom + MC model)

  • Tee

    *SIGH* still waiting on the iPhone 4 jailbreak. good job though.

  • Vincent

    Great news for us!

  • New bootrom iPhoner

    I'm on 3.1.2 new bootrom with tethered JB… Wouldn't mind this coming out. SHSH blobs are saved.

    But we have to wait and see, if there ever will be untehtered JB for new bootrom? 🙂

  • Spirit Jailbreak allowed you to jailbreak iPhone 3.1.3 or iPhone 3.1.2 without tethering.

  • New bootrom iPhoner

    Oh, sorry for my mistake. What I ment is will there be untehtered JB/Unlock for iOS4. 🙂

    But atleast I'm not in hurry to get iOS4. Will stay on 3.1.2 with Blackra1n as long as it's needed… Heh.

  • CoZze02

    Hahah where have you been, living in a cave. Use spirit dumb ass haha.

  • Same I am?

    I agree with you! I've been bored with my iPhone 4 and I'm waiting to have all of my custom features that I had on my 3g. I keep seeing post about jailbreaking the 3g and 3gs….where's the 4?

  • Lewis

    I can't get snowbreeze to work for my 3GS old bottom I followed the instructions to the T created a custom 4.0 Ipsw file but when restoring iTunes ends in error 1600 about 2 min into it. Tried with iTunes 9.2 then downgraded to 9.1 same results. Seems like others have the same issue with no solution. My only solution was to upgrade to 4.0 stock. Looks like I'm out of luck now correct? This wouldn't update bottom wouldn't?

  • AF

    Does that method really work with the new bootroom? Witch bootroom arevyou on?

  • Hmmm i see

    looks like ill be waiting for comex 4.0 JB.
    dont have 3.1.2 shsh. on 3.1.3 with comexjb.

    am surprise the is no way for cydia people to release a custom 4.0 onto cydia to install straight over 3.1.3jb OS

  • D3@th


  • Anshul

    does this mean that soon i'll be able to jb my ios 4 with newer bootrom ??

  • superfreak

    I completely agree with you. I jailbroke my 3GS with Spirit. It got updated to 4.0, and now I can't jailbreak using any of the tools out there because I used Spirit to jailbreak.

    Comix….. C'mon…. Comix…..

  • Jimmy

    I have iphone4 I want a freaking jb for it now please work on that before the older models

  • dkhan

    They may never release one. Remember they do this for free… People crying whining and griping at them like you and D3@th sure wont motivate them to work on this any faster. If you really want it that bad, you can learn to code yourself and write one. Beggers can't be choosers.

  • 3GS, old bootrom & was previously j/b with Spirit. Tried Snowbreeze & got 1604 error. None of the guides show a solution for that, had to upg to iOS4 because was stuck in recovery & couldn't get out of it with any of the guides i found online. forecast shows that I still have old bootrom but not sure how reliable that is. Would really like to jb/unlock this damn thing so that i can sell it & go to the iPhone 4 already. The profit is in the jb/unlock, anyone out there with a solution for this?

  • labrat1028

    You're full of it! Not doable with the new bootrom.

    Try downloading the Crispy Tech cooked IPSW. I couldn't get sn0wbreeze to work on my 3GS but didn't have any problems installing this. use google to find it.

    hope this helps…

  • cdeckel

    Seems like there is a manual way to do this.
    you can read here, it was posted by ih8sn0w:

  • RiCo

    Damn I just want my 3GS fw 4.0 jailbroken I'm not feelin the basic iPhone

  • somename

    It's not that you can't jailbreak because you used Spirit. It's because you updated to 4.0 – there's simply no jailbreak that works on a 3GS that is already on 4.0

  • somename

    OMG, you can't use all your stolen apps for a few more weeks … This must be pure torture for you.

  • i know how you feel man, its like the phone`s naked without the jailbreak. dev team need to stop focusing on new hacks and finish off bringing us the jailbreak for all devices.

  • I'm running windows 7. just put on itunes how do i downgrade to itunes 9.1 to be able to app sync my cracked ipa's into itunes. When i had itunes 9.1 it showed in there now in 9.2 it won't let me add them. I'm still on 3.1.3 5.12.1 JB wanting to go up to 4.0 and JB after that. Any Help would be great.
