Alright, I've got 2 3DSes and I had both of them with me the other day while I was shopping. after I left the store (I sat down for a minute at the store and checked out a nintendo zone to see if there was anything special about them) I noticed that my blue 3DS had gotten a streetpass from someone I didn't know, and the one i was playing on didn't. I kept them both on and in sleep mode in my pockets, but I'm unsure if the streetpass was while I was playing or not. The only noticeable difference between the two is the blue one that received the streetpass has the Nyko extended battery, and the black one does not. i've also noticed that it takes a while for swapnotes to be sent/received. Is this normal? Is there anything I can do to try and make sure that my black one has the same range as my blue one?
