I have an advantage to a semi-tethered jailbreak. In the past, if you were jailbroken and wanted to watch Sky Go you'd be stuck and would have to miss the big football game. But with semi-tethered, all you've got to do is turn your phone off and back on again and you're back to stock so you can watch the big game. Then once the games over, simply re-run Yalu and you're back jailbroken. Result!
