By now, you've probably heard of the 3DS error message covered here, or have potentially even encountered it for yourself. What's Nintendo's stance on this? I'm glad you asked.
"If anyone is experiencing any problems with their Nintendo 3DS console, we recommend that in the first instance they download and install the latest system update, now available online. If the problems still persist we recommend they contact their local Nintendo Customer Service center to investigate the problem further."
At least in the case of Nick, he says he's received an error after downloading the update Nintendo is referring to here. Additional updates are on the cards, perhaps?
