Mine went to preparing to ship today. Now here's a question - really I want a space gray model, and I was only able to order the silver. So I was going to wait on line tomorrow to try to get a space gray 6+. This is not an upgrade, I'm buying outright. So even if i've gone into preparing for shipment, do you think I'd still be able to buy one tomorrow morning and then just return the one that's being shipped when it arrives?
