Anyone know of a opaque black rubberized back cover made specifically for the iPad 4th gen? It also needs to be compatible with the smart cover. http://www.ebay.com/itm/280994278088?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Something like this but made for the 4th gen. I haven't had any luck finding anything. Thanks all.
