i suppose. but i've just ordered my DSTWO and wouldn't know until a few days later, and if i need to borrow a DS original/lite then i should start looking around now
what firmware version of the 3DS would allow for DSTWO update? mine (out of the box) is 4.2.0-9E, and i'm not sure if i can find someone with a DS original/lite if i have to go that route
