I've decided since iPads are taking 2+ weeks to ship, and I cannot buy mine until a week or two from now, to do this. Because I do NOT want to have the limited 2GB/$25 data plan when I buy my iPad... I want the 3G unlimited, but obviously how can I do that when I don't have an iPad in my hands right? I plan to purchase an iPad SIM card from AT&T retail store. (Will they ask for proof that I own an iPad? Will they just sell it to me, with no questions asked?) Then I will take that SIM card to an Apple Store, and take the SIM out of a display iPad, and stick my SIM in (LOL...) and activate it quickly with Unlimited. But Apple Stores always have security guards watching the sales floor, and they always seem so mean and quiet and unfriendly... Will I get in trouble for this? I don't want to get yelled at in front of countless people.
