As reported earlier by one of our authors (Sanix) Jailbreak And Unlock Latest IPhone 3.1.3 With Sn0wbreeze 1.4, now is the time to guide you through to jailbreak iPhone 2G, 3G and iPhone 3GS on latest iPhone firmware 3.1.3 using Sn0wbreeze – V1.3. Here I would like to mention that iPhone 3GS users with older bootrom (non-MC model) will be able to jailbreak successfully, on the other hand iPhone 3GS users who have upgraded to the stock 3.1.3 still need to wait.
What all you need is:
· Sn0wbreeze – V1.3
· Latest version of iTunes (9.0.3)
· Original iPhone OS 3.1.3 for your version of iPhone
Follow step by step guide to jailbreak your iPhone 2G, 3G and iPhone 3GS (old bootrom only)
Open Sn0wbreeze and check “Simple Mode”.
Now you will be asked to select the .ipsw file for your device. Click on “Browse” and select already downloaded 3.1.3 firmware .ipsw file for your version of iPhone. After verifying your .ipsw file you will see the following screen.
When asked click on “YES” to activate your device for hacktivation. If you are on official carrier like AT&T or O2 only then click “NO”.
Sn0wbreeze will create the custom jailbroken .ipsw file for your version of iphone that will be restored in later steps using iTunes.
Now use the same old procedure to restore your iPhone to this custom firmware. For new users, open iTunes, click your device as can be seen in the sidebar and then press and hold “Shift” key (from the keyboard) and click “Restore” button. You will get a pop up window asking you select your custom firmware. Select your custom firmware that was created in the previous steps and click on “Open”.
That is all for you, now iTunes will do the rest to install jailbroken 3.1.3 OS on your device. During installation your iPhone will show a progress bar pointing out installation progress. Once custom firmware is installed successfully your device will automatically reboot and here you go, your iPhone is now running on jailbroken 3.1.3 firmware.
