Hey guys, while browsing Best Buy I saw an open box iPad 16gb WiFi for sale, couldn't help myself and picked it up at 10% off. Off the bat, all the iPad's shrink sleeves for the iPad, charger, and cable were gone. But fwiw, the iPad is perfect, even better than the one I initially bought. Anyway, I went to check the receipt and the product has already been registered for warranty. Where do I contact Apple to update the information for the warranty ands send them a scan of my receipt? Or should I just call them? I tried registering the product, but it did not give me an option to submit verification.
