Before we get started, please realize the new jailbreak is limited on things it can and cannot do. You’ll have the usual access rooting your device would have. For one, you may run a custom OS and install unsigned apps. But, as beta utility, there is still work to be done. Hulu and Netflix, for example, are still unable to stream from the device’s browser.
