A SemiTethered jailbreak is normally a tethered jailbreak with a package installed that allows you to reboot with limited use. You must perform a tethered boot (see video for explanation) to regain full functionality to your jailbroken device. Much better than a tethered jailbreak, but not quite as good as the untethered variety.'
