The iPad 3 is still weeks away from being announced, but Chinese tech blog M.I.C.gadget managed to snag a back shell for the iPad 3 from “one of our most reliable sources.” As you can see from the pics after the jump the case is slightly thicker than the svelte iPad 2 back panel. The next-gen tablet still has the tapered styling of its predecessor. It just looks like a slightly overweight iPad 2.
