Always dreamt of a Apple notebook with built-in WWAN? Looks like today's your lucky day: a prototype MacBook Pro just surfaced on eBay, replete with a SIM card slot and retractable antenna in tow. Expecting a nonfunctional parts machine off Craigslist, its newfound owner managed to resuscitate the 2007-esque gizmo into booting, but was unfortunately unable to coax any GSM goodness from the thing. According to the seller, regular MacBook Pros from the era contain the same (but unused) solder points for the SIM card as the proto, lending credence to the notion that Cupertino might have seriously considered a 3G variant. Either way, if you've got a knack for rare Apple collectibles, or feel the need to ogle and some red-colored innards, hit the source below.
