I ordered through verizon, but I gotta say I'm regretting it. They promised people across the country that ordered at 5 on the 11th that they'd be shipping the orders to the customer directly from their warehouse via 2nd day fedex. needless to say, I and many others don't have our iPads. (I've seen a few people get theirs, but for the most part most seem to have not yet.)
They also can't track the orders and won't let you cancel the order. Oh and they charge your card as soon as you order (not when it ships)
