Well I tried with an English HGSS that I bought last July. My DSi XL is also an English one bought july 2010. I have not found the option for WPA/WPA2. I tried connecting to wi-fi through the DSi menu but it failed again so it seems nintendo has screwed XL users over by not giving us WPA/WPA2.
It still baffles me how my Wii can connenct to wifi and internets which I bought in '07 while my DS from 2010 can connect to internets too but not wifi.
