    Step 5: After the reboot, your iPhone is jailbroken. You can now find a Blackra1n icon on your iPhone springboard. This is an optional but recommended step, since the whole purpose of jailbreaking an iPhone was to use applications not allowed by Apple.

    Tap on the Blackra1n icon on your iPhone. On the next screen, you will be asked to choose an installer of your choice that will allow you to install and use any application you want. Choose Cydia and then press the Install button.

    Step 6: Once installation is complete, your iPhone will re-spring and you will find the Cydia icon on the iPhone screen (to get started check out our Cydia Guide). Tap on the Blackra1n icon again and on the next screen choose Uninstall Blackra1n. This will remove the Blackra1n icon from the iPhone.

    uninstall blackra1n 

    Tapping on the Uninstall Blackra1n will only remove the icon and not the application.

    Congratulations! You are now in the list of successful and legal users of unlocked iPhones. For any help or queries while jailbreaking or unlocking your iPhone, feel free to ask me.
