How to Jailbreak and Unlock iPhone using Geohot Blackra1n and Blacksn0w

We had recently written about the release of Geohot's iPhone jailbreaking tool Blackra1n. 

Here is a short tutorial that you might find useful in using these tools to jailbreak and unlock your iPhone 3G or iPhone 3GS on your Windows PC.

Some important points to note before we start:

  • Hacking your iPhone could void its warranty. So please proceed with caution and at your own risk.
  • Make sure that you have iPhone OS 3.1.2 installed on your iPhone. 
  • The jailbreak requires 05.11.07 baseband.
  • If you have a new iPhone 3GS (updated Bootrom), BlackRa1n only supports a tethered jailbreak. This means that once jailbroken you should not let your battery die. If it does die you will need to reconnect it to the computer and use BlackRa1n to boot it. 
  • Please take a backup of your iPhone, refer to this post for more details.
  • After you have successfully jailbroken your iPhone, please checkout our article on tips to keep your iPhone secure.

Step 1: Visit Blackra1n website and choose the Blackra1n software for Windows by clicking on the Windows logo

Step 2: Download blackra1n.exe (opens download link) 

Step 3: Connect your iPhone or iPod to the computer and run the downloaded blackra1n executable file

Step 4: You will now be shown a button that reads 'Make it ra1n'. Click on the button to the jailbreak process
