i know about the SS version and I was wondering the same thing regarding that ROM. I don't know what the advantage would be to have the newest N1 rom ported to the Droid over having the newest build actually made for the Droid.
I know some people might think that the frf91 is better than the 84b but I am pretty sure the developers like Chevy know that is not the case and that the FRF91 is the N1 build. So I would think the 84b would tend to run smoother than any build made for another phone. Maybe i am missing something.
