Download Sn0wbreeze V1.5 and Jailbreak iPhone 3.1.3

Buzz It

Sn0wbreeze 3.1.3 V1.5 has been released which adds support for iPod touch 2G (older non-MC model). For those of you who don’t know, Sn0wbreeze is a jailbreaking tool like PwnageTool for iPhone and iPod touch which can be used to create custom .ipsw files. But unlike the PwnageTool, Sn0wbreeze is fully compatible to work with Windows machines.

Read more for the jailbreak guides.

Follow the simple step by step guide below to jailbreak your iPhone 2G, 3G and iPhone 3GS (old bootrom only) on iPhone firmware 3.1.3 using Sn0wbreeze. This version of Sn0wbreeze is for iPhones only. iPod touch 1G/2G (older non-MC models) can use redsn0w to jailbreak on 3.1.3 firmware. iPod touch 3G is currently not supported. Guides for jailbreaking iPod touch 1G/2G (older non-MC models) can be found here.

I would strongly suggest iPhone 3GS users to stay away from this release as this release like all previous versions sends iPhone 3GS into an infinite loop after first reboot. If you have a Mac, I will strongly suggest you to use Dev-Team’s PwnageTool 3.1.5 which can jailbreak iPhone 2G, 3G, 3GS (older bootrom and with baseband 04.26.08).

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 and the original iPhone OS 3.1.3 for your version of iPhone (download links given below). Move all these files to your desktop.

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

Step 5: Sn0wbreeze will now ask you to browse for your .ipsw file. Select the correct 3.1.3 firmware .ipsw file by clicking the “Browse” button. Sn0wbreeze will verify the selected file and then will present you with following screen.

Step 6: Click on "Yes" when Sn0wbreeze asks you “Do you want to activate your iPhone?” for hacktivation. Click on “No” only if you are on an officially supported carrier like AT&T.

Step 7: 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 3.1.3 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 3.1.3. 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 firmware 3.1.3 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 firmware 3.1.3.

How to Unlock iPhone 3G/3GS on 3.1.3:
You can now follow the tutorial/guide posted here or here to unlock your iPhone 3G and 3GS (old bootrom only) on firmware 3.1.3 using ultrasn0w or blacksn0w respectively.

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 firmware version 3.1.3 by restoring the backup that you made in Step 2 from iTunes.

Note for iPhone 3G and 3GS Users (New Bootroms): We strongly suggest that you stay away from this official upgrade until and unless the DevTeam or George Hotz releases new jailbreaking and unlocking tools for 3.1.3 firmware. We will let you know when it will happen.
