In this instructable, I will teach you how to jailbreak on IOS 7 or later version. Now, you can do this on Mac and Windows, but if you try to complete this process on Windows, you will have to download iTunes, which is a considerable size. On Mac, it is pre-downloaded of course, so you don't need the extra work. Anyway, lets begin.
Step 1: Pangu Download
Now the software to download for you to jailbreak is called Pangu. It is a pretty small download, won't take more than five minutes at the most. After you have downloaded it, start the .dmg file and open. I don't know how it will look on Windows, but on Mac, it will show the Pangu icon. Double-click it and if your iDevice is not hooked up to your laptop, it will say, "Connect iDevice", or something. Anyway, connect your iDevice and press Jailbreak. Now, throughout the download, you will need to do some steps. It will ask you to open the Pangu app that appears on your iDevice, unlock it, and it will restart. Make sure your iDevice does not have a password on it for now, and you will need to change your date. It will show you what to change it to before you press Jailbreak. And that is basically it.
Step 2: Extras and Warnings
Now besides Cydia, and downloading any app for free, there is also iApp and many other extras you can download. iApp allows you to get any in-app purchase for free, so you can own any game. Also you can get different home screens, android lock, and many other things. There is a moviebox where you can download and watch the latest movies in theaters. Anyway, you also need to be warned. If you download something which is not the right software for your version, your iDevice will get bricked. Basically you will have to restart your device, and try to jailbreak again. It has happened to my brother twice, and for some reason I can't jailbreak his device again I don't know why, but it happened. I know that iCaughtyouPro is the wrong version for you, so don't download that. So, remember to know your version, and the software of the things you download. You have been warned.
