I trust resellers as far as I can throw them, frankly. They're bottom-feeders, IMO, and some have been known to string along buyers with promises they honestly can't fulfill, just to make a sale.
Unfortunately, there's little to differentiate one of their store-fronts from VZW's, due to the promotional materials and props VZW sends to them. So, it wouldn't surprise me if these "pre-orders" are just another way to snag unknowing customers into getting their cash early from them, and then sending their merchandise to them well after Corporate VZW starts selling their products.
Just sayin'...
