When you say reboot you mean a full Power Off right? So if you wanted to use z4root to temporarily root to use the wireless tether that would be a easy solution right? I have my INC rooted with unrevoked but, my wife doesn't want me to root her INC but she would like to use the wireless tether to connect her rooted Nook to the internet.. I am thinking that this may be the answer. Someone correct me if I am wrong.not that I know of, z4root will only temporarily root the dinc, once you reboot it goes back to stock no root state.
I just rooted with the new unrevoked 3.22 it was so easy.
now im trying to figure out about custom roms
