Well, it looks like you won't have to wait until 8:00am tomorrow to possibly get your hands on the new iPad after all. Walmart has now confirmed that it will begin selling the 16GB WiFi-only model tonight at 12:01am local time at all of its 24-hour stores. That includes both the black and white versions, as well as the now $399 iPad 2 if the whole Retina display thing isn't for you. Of course, there's no guarantees that you'll get one if you show up -- Walmart says it only has a "limited supply."
