I'm just a newbie that didn't think he'd want to root his phone and then figured out a good reason to do it, and now i'm looking for the least painful way of backup up the last week of playing with my new phone.
Welcome to the AndroidForums!
Not a dumb question at all. I don't actually know the answer... I've not stayed on 4.0.1 long enough to save a Nandroid for testing like this.
I'm pretty sure that Jay (saurik) only built and tested this on 4.0.2... Did you not ever receive a 4.0.2 OTA?
It would simple enough to try it to see...you'll either end-up rooted or you won't
(and if you do get root, you'll be able to easily un-root, too). The act of rooting (in this case, anyways) is simply installing the su and Superuser.apk binaries on your phone (so you don't have
to use them, even if you do root).
Cheers and let me know!
