Blutek via eBay offers the Unlocked Apple iPhone 6 16GB Smartphone for GSM Networks in Gray for $644.99 with free shipping. That's the lowest total price we could find by $130, although we saw it in another color for $5 less in November. It features an Apple A8 processor, 4.7" 1334x750 Retina display, 8-megapixel iSight camera, and 1080p video capture with 60 fps video shooting (240 fps shooting at 720p slow motion playback), 1.2-megapixel FaceTime HD camera, 802.11ac wireless, and Bluetooth 4.0.
