I've learned that original (and Lite) Nintendo DS systems do not support WPA/WPA2 Wifi encryption, but the newer hardware (DSi, 3DS) does.
I've also learned that this only applies to newer games, and that older games require WEP, even on newer systems.
Finally, I've learned that Pokemon Black and White do, nominally, support WPA2 encryption.
However, I've had a few sources tell me that this only applies to a subset of features, and to battle or trade over Nintendo WFC I'll have to fall back to WEP.
Can someone either confirm that this is the case and tell me what I won't be able to do over WPA2, or set me straight and confirm (via experience, please) that everything works over WPA2?
Sadly I don't have a DSi or I'd puzzle this out myself, but this is a deciding factor in whether I get a 3DS at launch or not.
