Jailbreak iPhone 3.1.2 Firmware with blackra1n



George Hotz (aka geohot), the kid who was the first to unlock the original iPhone back in 2007 and then iPhone 3GS in July of this year is back! This time he is the first one to release jailbreaking solution for the new iPhone 3.1.2 Firmware for all devices through his new tool called blackra1n. blackra1n is a software tool which can jailbreak (not unlock) all iPhone’s (iPhone (Edge), iPhone 3G and iPhone 3GS) and iPod touch’s (iPod touch 2G and 3G) running on firmware version 3.1.2. blackra1n is currently for Windows only, a Mac version of this app can be expected soon.
So, what is blackra1n? blackra1n is a 30 second ALL device 3.1.2 jailbreak. Even the ipt3, but the ipt3 is tethered. In order to boot it, just rerun blackra1n.

Follow the steps below to jailbreak all iPhone’s and iPod touches on OS 3.1.2:
Note for iPhone 3G and 3GS: Do NOT upgrade to iPhone 3.1.2 yet if you want to keep your unlock as doing so will result in upgrade of your baseband which will make it almost impossible for you to unlock.
Step 1: Download and install the latest version of iTunes (download link given below).
Step 2: You will now need to first update/restore to the original iPhone OS firmware 3.1.2 on your iPhone by using the latest version of iTunes. Download link for iPhone Firmware 3.1.2 is given at the end of the post.

Step 3: Download blackra1n for Windows (download link at the end of the post).
Step 4: Start blackra1n app. If you are on Windows 7 or Vista, run the app with “Windows XP Compatibility” mode by enabling it from the “Properties” tab to avoid any errors during the jailbreak process.
Step 5: Click on “make it ra1n”:
