Like the title says, I might be able to use wifi again for DS battles. I would still need to confirm this with a DS battle, so if somebody wants to battle me to confirm this, or if they just want to battle and don't mind if somehow I get dc'd, feel free to challenge. My Pearl FC is 3223 8060 6992. I won't be battling on SoulSilver for a while still.
If I do have working wifi again, I will set up a challenge board for people as I know a few people have wanted to battle me in the past.
