Jailbreak iOS 4.1 on iPhone 3GS New Bootrom with Sn0wbreeze 2.0.1 [Custom Firmware Windows]

Sn0wbreeze 2.0 is out! Just like PwnageTool for Mac, you can now cook custom firmwares of iOS 4.1 on Windows without upgrading the baseband, which ultimately means that you can use ultrasn0w unlock software to unlock your phone on the older baseband.

Sn0wbreeze 2.0 supports following devices:

• iPod touch 1G (Must be jailbroken on any firmware version)
• iPod touch 2G (Non-MC Model, Must be jailbroken on any firmware, if not, then use iREB from here)
• iPod touch 2G (MC Model, must be on iOS 3.1.2. Does not need to be jailbroken on 3.1.2)
• iPod touch 3G (Must be previously jailbroken on 3.1.2)
• iPhone 2G
• iPhone 3G (Must be jailbroken on any firmware, if not, then use iREB from here)
• iPhone 3GS new bootrom (Must be previously jailbroken on 3.1.2)
• iPhone 3GS old bootrom (Must be already jailbroken. If you are jailbroken using Spirit or JailbreakMe, install Spirit2Pwn from http://repo.woowiz.net.

NOTE: Sn0wbreeze 2.0 WILL NOT jailbreak iPhone 4, iPad and iPod touch 4G.

Instructions are as follows:

Step 1: Download and install the latest version of iTunes.

Step 2: Now start iTunes and sync your iPhone with your PC so that it backs-up all your important data including settings, apps, music, contacts and photos.

Step 3: Download Sn0wbreeze 2.0 and the original iOS 4.1 firmware file for your version of iPhone or iPod touch (download links given below). Move all these files to your desktop.

Step 4: Start Sn0wbreeze and select “Expert Mode”.

Step 5: Sn0wbreeze will now ask you to browse for your .ipsw file. Select the correct iOS 4.1 firmware .ipsw file by clicking the “Browse” button. Sn0wbreeze will verify the selected file and then will present you with following screens.

Step 6: Now if you are on iPhone 3GS (New Bootrom) or iPod touch 3G, make sure you hit “General”-> and check “Use iBooty Method (3.1.2 Installation Required!).

Also check “Activate The iPhone” if you are on unofficial carrier and want Sn0wbreeze to hacktivate your phone.

Step 7: Now simply select “Build IPSW”. Sn0wbreeze will now create the custom .ipsw file for your iPhone which will be jailbroken.

Step 8: Now you will have to restore your iPhone to this custom firmware 4.1 that you just cooked using Sn0wbreeze for your iPhone. Click on your phone from the sidebar in iTunes and then press and hold left “Shift” button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release the “Shift” button.

This will make iTunes prompt you to select the location for your custom firmware 4.1. Select that custom .ipsw file and click on “Open”.

Step 9: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new iOS 4.1 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully jailbroken iPhone running on iOS 4.1.

How to: Unlock iOS 4.1 (Old Baseband): Once you are done with the jailbreak, you can follow our step by step guide posted here tounlock your iPhone on iOS 4.x, on older baseband using Ultrasn0w.

Step 10: Once you are done with the unlocking and jailbreak process. You can now restore all your settings, apps, music, contacts and photos to the newly installed iOS 4.1 by restoring the backup that you made in Step 2 from iTunes.

UPDATE 1: Sn0wbreeze 2.0.1 has been released which fixes iTunes Error 37 when restoring to custom iOS 4.1 firmware. The download link for Sn0wbreeze posted below has been updated for version 2.0.1.

No iOS 4.3.4 Untethered Jailbreak Anytime Soon!

i0n1c sent out a couple tweets concluding that an iOS 4.3.4 untethered Jailbreak will not be availableanytime soon (if ever). It appears as if Apple hasn’t just fixed the holes used in previous untethered Jailbreak’s they have beefed up their security as well. Meaning it will be a lot harder for developersto exploit the iPhone, iPod Touch and iPad to create an untethered Jailbreak.

Personally I do not see an untethered iOS 4.3.4 Jailbreak being released. The iOS 4.3.4 firmwaredoes not come with any new features besides patching Comex’s PDF exploit. Thus, with the iOS 5firmware right around the corner, I would think it would be a waste to use an untethered exploit on the iOS 4.3.4 firmware.

While you cannot Jailbreak the iOS 4.3.4 firmware untethered, you can Jailbreak the iOS 4.3.4firmware tethered using RedSn0w 0.9.8b3. You can Follow our tutorials listed below if you are interested in Jailbreaking your iPhone, iPod Touch or iPad running the iOS 4.3.4 firmware tethered.

UNLOCK iPHONE 3gs/4/4s TO iOS 5

The question that is constantly on everyone’s mind is when will the untethered iOS 5 Jailbreak be released? Though such a question is not easy to answer, we have heard mixed information from numerous developers across the Jailbreaking community about the iOS 5 untethered Jailbreak. Thus, I am going to do my best to provide a clear and concise answer to when the untethered iOS 5 Jailbreak will be released (or at least it’s current status at this time).

Before we start talking about the iOS 5 untethered Jailbreak, however, we are going to clear up some other frequently asked questions.

Can you Jailbreak the official iOS 5 firmware?

Yes. You can Jailbreak the official iOS 5 firmware with the RedSn0w Jailbreaking tool (compatible with Mac OS X and Windows) as well as the Sn0wBreeze Jailbreaking tool (compatible with Windows). At this time, however, when you Jailbreak your iPhone, iPod Touch or iPad running the official iOS 5 firmware it is a tethered Jailbreak. Meaning that every time you loose power to your iPhone, iPod Touch or iPad you will need to plug your iDevice back into your computer and re-boot using RedSn0w/iBooty. If you would like to Jailbreak the iOS 5 firmware tethered you can click here.

Why Jailbreak the official iOS 5 firmware?

As the iOS 5 firmware contains over 200 new features for the iPhone, iPod Touch and iPad, a lot of people are wondering is it still worth it to Jailbreak the iOS 5 firmware. My answer to this question is without a doubt – Yes. The iOS 5 firmware comes a ton of new functionality that really improves your iDevice; Because there is so much new functionality it gives developers even more ideas on how to tweak the iPhone, iPod Touch and iPad for the better. Take Notification Center tweaks for example. The stock iOS 5 notification center is great but it becomes ten times better when you have the ability to install 3rd party tweaks. And even though the iOS 5 firmware is a great improvement in the iOS operating system it is still lacking functionality that tweaks such as SB-Settings provides.

Can you Jailbreak iOS 5 Untethered?

At this time you cannot Jailbreak the iOS 5 firmware untethered. While there has been paid software circulating the Internet promising an untethered iOS 5 Jailbreak (like FastRa1n v5.0), it is nothing more than a scam to take your money. Do not be fooled, at this time, there is no way to Jailbreak the iOS 5 firmware untethered.

Note: iPhone 3GS users can Jailbreak the iOS 5 firmware untethered if they are running the old bootrom.

When will iOS 5 Untethered Jailbreak be released?

The iOS 5 untethered Jailbreak is currently being worked on by numerous developers across the Jailbreaking community such as the Chronic Dev-Team. According to P0sixninja (head of Chronic Dev), who spoke at MyGreatFest, there are numerous iOS 5 untethered exploits available. MeaningJailbreaking the iOS 5 untethered should not be a very big issue. It is just a matter of converting one of their exploits into a usable Jailbreaking solution such as GreenPois0n. Additionally, i0n1c (responsible for an untethered Jailbreak in the past) mentioned that the iOS 5 untethered Jailbreak was already covered by other people.

We will keep you updated on the status of the iOS 5 untethered Jailbreak. Until that time please stay tuned…
