So the iPhone 4 Jailbreak is on its way and it is coming soon. I took the time to make a video on the age old question, "What is Jailbreak?". This video explains some of the things that will be open to you and available once you do Jailbreak your device. Your device will be able to have endless possibilities to what you can do. You can unlock your phone to use on any carrier, or even change your entire UI. There will be an abundance of videos being made here for what you can do, once the Jailbreak is released.
