Engadget found an image of a silicone case for the iPhone nano. This could be a fake, but the gadget site writes these third-party renders have turned out accurate before..
There's something just a little skeezy about basing predictions for Important New Apple Products upon nasty renders of protective case mockups from China. Still, they've panned out astonishingly nicely before, so we'll just have to suck it up. iDealsChina is reporting that XSKN is not-so-secretely working on a silicone skin for the upcoming "Nano iPhone" (or, more likely, iPhone nano) a shorter, chubbier version of the iPhone 3G. According to iDealsChina sources, the phone will apparently sport EDGE data, but otherwise seems unsurprisingly identical in specs to its forebears, other than the obviously smaller screen.
