Glad to hear you are squared away now. I wonder how many others bought iPads with the same problem. At least those who are still on the fence will get the opportunity to buy refurbed units in the not too distant future :D.
Enjoy your fully functional iPad ;).
Every first gen product may have a few that slip quality control. Good thing apple stands by their products.
The point is if you have a serious problem make sure one takes back the ipad to be checked as you have done asap
