I bought a Wii last week from W***Mart and upgraded to the newest system version. After discovering that you guys have hacked this thing to pieces, I decided that I'd love the security of using backups via my thumb drive or dvd backups. Are brand new Wii owners that have upgraded to 4.0 completely out of luck? I've installed nothing other than Nintendo's suggested update. If so, maybe I can get an exchange (I've had it for a week, and have the receipts, the boxes, etc).
