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.

UPDATE: An updated version of this guide for blackra1n RC3 with blacksn0w can be found here.

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.

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 5: Click on “make it ra1n”:

  1. The solution for this is simple, you will need to place the Blackra1n executables in the Apple folder under Common files in Program Files. The folder would be located in the following locations:

    32 Bit – C:Program FilesCommon FilesAppleApple Application Support

    64 Bit – C:Program Files (x86)Common FilesAppleApple Application Support

    Once you copy the blackra1n executable to the above folder, create a shortcut for it on the desktop and double-click it to run it as usual.

  25. For all having
    any difficulty unlocking AT&T phones, all that’s necessary to complete is
    head to attiphoneunlocking.(com), we can unlock all AT&T phones.

  26. If any of you
    AT&T users is having an arduous time attempting to unlock AT&T
    devices, you can take a look at attiphoneunlocking.[com], it’s among the few
    sites that’s still able to unlock AT&T phones after AT&T had its
    database renewed, which means AT&T does’t permit the access for their
    database for a lot of cheap unlocks.

  27. I understand a
    really good site for those who want to unlock AT&T devices, it’s
    attiphoneunlocking.{com}, also the best AT&T unlocking site I’ve ever use

  28. I understand a site that’s still able to ՍΝᏞΟᏟΚing AT&T phones after AT&T denied the access of numerous ՍΝᏞΟᏟΚing sites for their database after the renew, which caused numerous սոⅼοсkings no longer working anymore. The site is just google atttiphoneuunlocking, it’s without doubt one of many fastest սոⅼοсking site you can find on the web nowadays.
