How to Unlock and Jailbreak Your iPhone 3G/3GS with Blackra1n RC3

If you have an iPhone 3G or 3GS running on iOS 3.1.2 and you want to unlock it for any carrier and jailbreak it for access to Cydia and other tweaks, you can use Blackra1n RC3, a simple and fast tool developed by George Hotz (aka geohot).

Blackra1n RC3 has unlock as well as jailbreak for iphone 3g and 3gs

Blackra1n RC3 can jailbreak all iPhone models (2G/3G/3GS) and iPod touch models (1G/2G/3G) on iOS 3.1.2. It also includes blacksn0w, which can unlock iPhone 3G and 3GS with baseband 05.11.07, which was previously not unlockable.

Here are the steps to unlock and jailbreak your iPhone 3G/3GS with Blackra1n RC3:

  • Download and install the latest version of iTunes from here.

  • Download the original iOS 3.1.2 firmware for your iPhone from here.

  • Connect your iPhone to your computer and launch iTunes.

  • Select your iPhone from the left sidebar and click on the "Restore" button while holding down the "Shift" key (Windows) or the "Option" key (Mac).

  • Browse to the iOS 3.1.2 firmware file you downloaded in step 2 and select it.

  • Wait for iTunes to restore your iPhone to iOS 3.1.2.

  • Download Blackra1n RC3 for Windows or Mac from here.

  • Run Blackra1n as an administrator (Windows) or with "Windows XP Compatibility" mode (Vista/7).

  • Click on the "make it ra1n" button and wait for your iPhone to reboot.

  • You should see a blackra1n icon on your iPhone's home screen. Tap on it and select "sn0w" to install blacksn0w, which will unlock your iPhone.

  • You can also select "Cydia" to install Cydia, which will jailbreak your iPhone and allow you to install apps and tweaks that are not available on the App Store.

  • Reboot your iPhone and enjoy your unlocked and jailbroken device.

Note: This is a tethered jailbreak, which means you will have to run Blackra1n every time you reboot your iPhone or it runs out of battery. Also, this method only works for iOS 3.1.2 and baseband 05.11.07. Do not update your iPhone to a newer version of iOS or baseband unless you are sure there is a compatible unlock and jailbreak available.



If you have successfully unlocked and jailbroken your iPhone 3G/3GS with Blackra1n RC3, you can now enjoy the benefits of having a fully customizable and versatile device. You can use any SIM card from any carrier, install apps and tweaks that are not available on the App Store, and customize your iPhone's look and feel to your liking.

Some of the popular apps and tweaks that you can install from Cydia are:
