When the untethered JB is released, will it be able to be run over the current semi-tether jailbreak to obtain a full untethered without restoring to a non-jailbroken state? I ask just because I am tethered on 5.0.0. My concern is that if 5.1 is released and I don't get a clean copy of 5.01 prior to the JB if I will be **** outta luck. Thanks.
