This may be a stupid question, but I need some advice. I want to JB to 2.2.1 (preserve baseband). I am currently JB 2.2. I just got an aluminum macbook (late `08 model). I cloned the HD from my old macbook, on which I successfully jailbroke my 3G. The cloned HD is now in my new macbook. I just read that the aluminum macbooks can't be used for JB yet, but do not know if that is a hardware or software issue. Because the HD is "old", is it safe to JB, or does the new aluminum body/guts mean I'm stuck?
