I just got my iPad Friday from Best Buy. It's a 3G 64gb. It was an "open box" on sale for $750. Sales guy said it wasn't a return, but its box was damaged during shipment. The box looked perfect to me and so did everything inside, but here's the strange part. I've been able to go on the Internet via 3G and I wasn't prompted by the AT&T website or asked about a plan?? I think it was in fact a return, but it appears to be working flawlessly. Any comments?
