So I made this video to help others Jailbreak their iPhones. Because about one year ago I tried to jailbreak my iPhone unsuccessfully.
What is this jailbreak I speak of? Well if you think of the term jailbreak you imagine a prisoner escaping from jail. Well that is essentially what you are doing with your iPhone you are breaking it out of jail and relaxing all the restrictions that Apple has placed on the iPhone. If you want to learn more about what is the difference between jailbreak and unlock you can read my article on it here. Jail breaking allows you to install Apps and configure your iPhone that would otherwise be locked down by Apple’s default settings. A good example of a great Apo that will install on a jail broken iPhone is Veency and you can see my video here.

Before attempting any funny business with your iPhone or iOS device, you should always do a backup in iTunes and you can find the video on how to here. Once you have backed up your iPhone and you are happy that all your data is safe you are ready to Jailbreak it.

Step 1. Go into your setting menu, general and turn off Auto-lock and Passcode Lock. Make sure both these settings are off as they may interfere with the jailbreak.
Step 2. Scroll up and go into About, and make a note of the firmware version.
Step 3. Download redsn0w from our downloads section here. There is a Windows and Mac version that you can download.
Step 4. Install redsn0w and run the application. Plug in your iPhone to the USB port and make sure the driver for the iPhone installs correctly. If it doesn’t try restarting your PC or Mac with your iPhone plugged into the USB port. This will normally resolve driver issues, because the driver detects the iPhone and installs the driver on start up.
Step 5. Make sure you iPhone is turned off and still plugged in.
Step 6. Ok you need to now put your iPhone in DFU mode. To do this you need to Hold down the power button for 3 seconds. Without releasing the Power button, also hold down the Home (bottom center)button for 10 seconds. Without releasing the Home button, release the Power button, BUT KEEP holding the Home button for 15 seconds.
Step 7. In the redsn0w program it should say waiting for reboot. And on your iPhone will say downloading jailbreak data. Once redsn0w says done you can actually disconnect the USB cable from your iPhone and it will continue to install.
Step 8. The iPhone should reboot and once it does this you can login and scroll across to your Apps and you should see a brown Cydia App. If you have this then you have been successful in jail breaking your iPhone.

One last thing I should mention, the jailbreak process does not always go smoothly. The most annoying error is USB communication error. You can see my video on how to fix this error here.

Good luck guys and have fun.
