Okay, i've completely misunderstood the wireless capabilities of the DS. i thought the WiFi and the Nintendo wireless were different radio technologies, and not just different protocols. It doesn't affect local area play, so i'm not really concerned.
Also, what happened to the alerter function? i haven't seen anything on Nintendo's revised DS site about it, but i remember reading that the DS could alert you when another user was in the area. Wasn't this on the old DS site? If not, i'm really disappointed, because this would be a great way to always have people to play with, build DS aware, and a DS community.
