I have a 3GS with the MB in the model number and I know it's the new boot rom because of the black rain JB which is if you had the new boot rom then you had to tether every time you wanted restart your phone which was the case for me.
Still waiting for a 3GS new boot rom un-tethered JB since day one. Will it happen for 4.0? Redsnow i thought someone said.
