I sent my console in last week to be "cleaned". Kudos to Nintendo for returning it in the 1-week period they said they would. However, IT STILL DOESN'T WORK!!!!! Same "can't read disk" error as before, 5 minutes after it's out of the packaging.
There's no way this is a dust problem, and Nintendo knows it. Unless they've decided to get into the game console cleaning business, something else is going on.
I'm just about done with Nintendo. This once-loyal customer has been abused enough.
