I preordered a few iPads today. They're not all for me, but I charged them all on my card. (Family / Friends paying me back.) Apple just called my house, which I'm assuming is because it's the billing address. (Although I never put my house phone number down, only my cell phone.) Is it normal for them to call? I saw the name show up on the TV's Caller ID, but couldn't answer it. My LAN phone was unplugged, so I'm not sure if the call won't show up or if the number I called is some automated company number. Anyway, just curious as to what they might be calling about. Maybe they think I ordered 7 iPads for myself, just because it's all from the same billing address. But where they're going are all to different people and different addresses. Not sure if this is a problem or not.
