If you think that might be you, read on for Gizmag's iOS 8 jailbreaking tutorial.
Before we get started, remember that this will void your warranty. Jailbreaking is fairly easy and you should always be able to restore your device back to a stock (non-jailbroken) state ... but this still isn't meant to be taken lightly. If the worst happens and your iPad turns into a $500 doorstop, only you are responsible.
... if you aren't comfortable with that risk, then we recommend you enjoy iOS as Apple intended it (which is pretty terrific these days) and move right along.
If you're sure you want to jailbreak, then of course you'll need to start with an iOS device. Any that runs iOS 8 through 8.1 will do. And yes, that includes the latest: the iPhone 6, iPhone 6 Plus, iPad Air 2 and iPad mini 3.
You'll also need a Windows PC. Or, if you have a Mac or Linux computer, you could run Windows in a virtual machine. As of now, though, there's no native Mac jailbreak tool for iOS 8.
