You can choose that later, when the real preorder starts.What would we be preordering, 3G/4G, wifi-only or even by choice (regarding mass-production preorder)? And I'll just assume it'll be on the Dragonbox Shop page, right?
I might preorder if I'm not super late and only get a number higher than 100, heh. Payment would take a few more days as well here though. Some cash would need to find its way onto the account first.
