These are step by step instructions how to jailbreak and unlock almost any iPhone instantly! No downgrading then upgrading! You can do the unlock from 1.1.2, 1.1.3, or 1.1.4. It will also jailbreak and activate as well as install Installer.app for you!

ZiPhone performs all these functions:
- Unlock will work on 4.6 BL or 3.9 BL
- Jailbreak will work on any OS version.
- Activation will work on any OS version, except for youtube on 1.0.X.
- iErase BL 3.9 Baseband

WARNING: THIS TUTORIAL WILL DOWNGRADE YOUR BOOTLOADER TO 3.9!

Double click ZiPhone.zip on your desktop to extract the folder ZiPhone..


Step Three
From the extracted ZiPhone folder double click ziphoneGUI.exe to launch the application.


Step Four
Make sure you iPhone is connected to the computer and that iTunes has detected it.

Step Five
You can now activate, jailbreak, and unlock,! Just simply click the Do It All! button.

The program will now load zibri.dat. Then it will search for the iPhone. Once found it will tell you to wait for approxiametly 4 minutes.
