Jailbreak and Unlock your iPhone 3G

In Uncategorized on March 28, 2010 by Sukrit

I recently jailbreaked and unlocked my iPhone 3G running baseband 3.1.2 . Jailbreaking is a great way to remove the Apple imposed obstructions and customize the iPhone. I can add themes, apps and do things as on my laptop.

These are instructions on how to jailbreak your iPhone 3G on the 3.1.2 iPhone firmware using RedSn0w for Windows.
This tutorial can be used to jailbreak before applying the BlackSn0w unlock to your device. 

Watch the Video!
For your convenience this tutorial is available in video format also. Click the Watch It button to view the tutorial!

*Note: this video uses an older version of RedSn0w but is still applicable

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here and place it in the Pwnage folder. Likewise, download the latest 3.1.2 firmware from below and place it in the same folder.

3.1.2 (3G): iPhone1,2_3.1.2_7D11_Restore.ipsw 

Extract the RedSn0w application from the RedSn0w zip file to the Pwnage folder.

Step Two
Connect your iPhone to the computer and launch iTunes. 

Select your iPhone from the list of devices on the left. Now hold down shift and click the Restore button. Restore is preferred as it won’t create any wasted space on your iPhone.

Navigate to the Pwnage folder on your desktop and select the firmware ipsw. Click the Open button to continue. 

Step Three
Once iTunes has finished updating your iPhone to the desired firmware you may launch redsn0w.exe from the Pwnage folder on your desktop.

Step Four
Once RedSn0w opens click the Browse button

Step Five
Select the firmware ipsw we placed in the Pwnage folder on our desktop then click Open

Step Six
Once the firmware has been verified click the Next button to continue.

Step Seven
From this window you can select the jailbreak options you would like. If you have already pwned your device check the Already pwned option. 

Verbose boot displays detailed information on boot of your device and is generally only needed by developers and advanced users.

Make sure Cydia is selected. For this tutorial we will also select Custom boot logo and Custom recovery logo

When you click to select each custom logo option a dialog window will appear asking you to select the image. Locate the image you would like to use then press the Open button.

*Remember the rules for boot logos are: RGB or Grayscale format with Alpha channel and dimension below 320×480. If you would like to use the iClarified ones they can be found here: Boot LogoRecovery Logo

Click the Next button to continue

Step Eight
Please plug your iPhone into the computer and make sure its OFF then click the Next button

Step Nine
RedSn0w will now guide you through the steps to get into DFU mode.

Hold down both the Home button and the Power button for 10 seconds.

Release the Power button and continue holding the Home button until RedSn0w detects the device.

Step Ten
Your iPhone will now reboot

Step Eleven
RedSn0w will then begin uploading the new RAM Disk and Kernel. 

Step Twelve
Once this is complete you will be notified that RedSn0w is done. Click the Finish button. After your iPhone finishes rebooting (5 minutes or so), it will be jailbroken with Cydia on the SpringBoard.

Your iphone is now jailbroken. Unlocking is now very easy.

Step One
Press to launch Cydia from your iPhone Springboard.

Step Two
Press to select Manage from the tabs at the bottom of the screen.

Step Three
Press the large Sources button.

Step Four
Press the Edit button at the top right of the screen.

Step Five
Press the Add button at the top left of the screen.

Step Six
Input http://www.blackra1n.com as the source address then press the Add Source button. Once Cydia has added the source press the large Return to Cydia button.

Step Seven
Press the Done button at the top right of the screen.

Step Eight
Press to select blackra1n.com from the list of sources.

Step Nine
Press to select blacksn0w from the list of packages.

Step Ten
Press the Install button at the top right of the screen.

Step Eleven
Press the Confirm button at the top right to begin installation.

Step Thirteen
Wait a few minutes for your CommCenter to restart and you will now be able to use the SIM card of your choice on your unlocked iPhone!

Your phone is now jailbroken and unlocked. I will be back with some apps and other cool tips and tricks to customize your iphone.
