I just noticed that when I pull out the Smart Cover from the ipad 2, there is like a burn stain on my ipad's left side when smart cover is connected. To my surprise, it actually came from the more stain of the magnet of the smart cover???? How is that possible??? My theory is that it might be when i charge my ipad 2 and the outlet where our electricity is flowing is kind of like having problems. Because sometimes when I am about to charge my ipad 2, there is a spark-like on the outlet.... Do you think it could be the reason why did i notice the brown burn like stain on both the side of my ipad 2 and the magnet of the smart cover???? please help me
