will my unlocked bl backup restore if im on locked bl at the mo

Im not sure.I unlocked my bootloader with FT,but in the DK thread he says that way is a "bypass" opposed to the "proper method"(the one with running a zip file beginning with q).It did once relock,but I cant remember if I reflashed or restored for it to happen.

Im new to all this phone stuff,my knowledge is more about sony psp and tomtoms.....
