- My puro smart cover did not work with my new ipad3. I read the ipad3 uses a different magnetic field sensor that is sensitive to magnetic field direction. To test this I removed the cover from my ipad and positioned it to the right op my ipad in portrait mode, the lid opening to the left. When I opened it, the edge of the lid covered the right edge op my ipad and voila, the ipad switched off. The malfunction of my puro was caused by the position of the magnet. I then cut a 1 inch opening thru the stiches of my cover some 3 inches from the top, pulled the round magnet using a pincet and put it back in upside down. When I tested the cover, it worked fine. A few stiches and the cover was good as new. Wish you happy sewing.
