I have a WiFi iPad, and LOVE IT. My internet at home, well, sucks. I have great 3G coverage at home, with good download speeds. So, I preordered a 3G iPad today. I hope AT&T sticks with the "unlimited is unlimited" data statement they made. Will the Apple Store take back my WiFi model? I am OK with a small restocking fee if they will. Or, is eBay the right move to make to recoop some of the money from my WiFi iPad?
