Just updated my system too. Had to do it through the e-shop. Tried doing it through the system first but got an error, then went to e-shop where it said there was an updated and it worked. Now I have video and a renovated Mii Plaza.
Nope, that's 3DSWare(Download Software or whatever it's called)is the message thing in the update?
Yay, I'm the first person on GBAtemp to get 3DS v.3.0.0.
