So, here's a question: I can't wait for untetherned jailbreak for 4.2.1 to come out. So, I've been thinking to jailbreak it with the current tetherened one. My primary goal is to install hackoulous package and install installous. Now, once the untetherned jailbreak comes out, would I be able to simply rejailbreak it? Would it be just as a simple update? Will I lose any programs that I have downloaded from Cydia or installous?
