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-secretly 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. They're also saying Apple plans to sell these at high volumes for low prices at hip spots like Walmart, that the company will (naturally) be unveiling the new handset in January at Macworld, and even go so far as to say that leaked photos of the device should be surfacing in the next couple of days -- we'll be keeping our eyes peeled. Check out another couple of tantalizing case renders after the break.
