Hi, I have a question about Street Pass on the 3DS. I plan on going out to the mall tomorrow and am bringing my 3DS with me, now if I want to collect street pass data all I have to do is leave my 3ds in sleep mode? Also the only things I have for my 3DS so far are Excitebike (Free classic), Pokdex 3D, Pokemon Black. So will I still gather anything from street pass with that said? Or no?
