In this post we will be using a free software called blackra1n to jailbreak your iPhone 3.1.2. Please note that jailbreaking voids our warranty, and we are not responsible for anything that happens to your iPhone as a result of following this tutorial.

Warning: If you have an iPhone 3GS it will be tethered, meaning you will need to connect your device to your computer and run blackra1n again every time you reboot (turn off and turn on) your iPhone.

1. Download the free iPhone OS 3 toolbar (on Internet Explorer, Firefox, or Safari) and install it.

2. Click the Downloads button and click on the Download blackra1n RC3 link to download it.

3. Connect your iPhone to your computer and open the blackra1n application.

4. Click the make it ra1n button.

5. blackra1n will now put your iPhone in recovery mode and display the above image of Geohot. While in recovery mode, blackra1n will jailbreak your iPhone.

6. Once blackra1n is done jailbreaking, your iPhone will reboot and you should see the blackra1n icon on your iPhone screen.

7. Tap the blackra1n icon to open it. You have the option of installing either Cydia, Icy, or Rock. Select the applications you would like to install and then click the Install button to install them.

8. Once you’ve installed the applications, restart your iPhone. To do that, just hold down the top button until the Slide to power off message appears. Slide the button, and wait for your device to turn off. Turn on your device and you should now see the applications you selected on your iPhone.

Congratulations, you have successfully jailbroken your iPhone, give yourself a pat on the back! Now you have access to a lot more applications and modifications that you will never see in the App Store.

Normally I don’t make tools for the general public, and rather wait for the dev team to do it. But guys, whats up with waiting until 3.1? That isn’t how the game is played. We release, Apple fixes, we find new holes. It isn’t worth waiting because you might have the “last” hole in the iPhone. What last hole…this isn’t golf. I’ll find a new one next week.

The Dev Team did not want to release their jailbreak early because they felt that it would benefit relatively few people and thought it would be best to keep the vulnerability out of Apple’s eyes for now. Unlike all the current iPhone and iPod Touch devices, the iPhone 3GS cannot always be jailbroken. Apple can permanently patch this with a simple update. Now that Geohot has released this jailbreak, Apple may be able to examine it and permanently patch the exploit in their next iPhone 3.1 update.

Update: Go to Jailbreak iPhone 3GS 3.0 with purplera1n for a step-by-step guide on how to jailbreak your iPhone 3GS. Its easy!

Note: The purplera1n jailbreak software is in beta, and Winterboard does not work with it. As of right now you can only jailbreak using Windows (it won’t work with Windows 7). You may want to wait until the Dev Team at http://blog.iphone-dev.org releases their jailbreaking software.
