Has anybody tried fiddling with the wireless functions? I've got a store bought Black in a DSi XL, and a patched White (U) on my M3i zero in my DS lite. After registering friend codes, they can see each other in union rooms and trade. They can call each other on the telephone thingy. But on the flip side, the wireless page always says "C-gear detected = 0", and the Entranet function doesn't work at all. So bits of wireless work, and bits of it don't, and I'm curious why. As long as I can trade back and forth, I can't say I care too much, but it's still a bit of a bummer I can't check out most of the multiplayer functions. If I had to guess, it's almost like the flashcard isn't able to perfectly handle all the functions that B/W has.
