Blog M.I.C. Gadget has acquired an interesting treasure from China, a 64GB iteration of Apple’s iPhone. Rumors of the existence of a high-capacity iPhone have been circulating the web for the last few days, but this is the first time we’ve been treated to crystal clear images and video of the handset. The device, for the most part, looks identical to the current iPhone 4, but bears its closest resemblance to the lost iPhone purchased by Gizmodo last year. The 64GB iPhone, which is being described as an “engineering prototype,” lacks the plus and minus engravings on the volume keys and the silver ring which the surrounds the camera lens is also absent — both omissions on Gizmodo’s model as well. The device has a model number 995-6049LL, is running iOS 4.1, and is not SIM-locked. The faux model number and FCC ID engraved on the back of M.I.C.’s device also match those found on the Giz model. The device certainly does seem to be authentic, and if so, our only question is whether this is what we should expect to see announced this spring, or if this is a pre-iPhone 4 release prototype. We’re hoping for the latter. Hit the jump to check out the video and a few extra images.
