With a new 2-year agreement, AT&T Wireless offers the refurbished Apple iPhone 5s 16GB Smartphone for AT&T in Space Gray, Silver, or Gold for $49.99 with free shipping. That's tied with our mention from three weeks ago and as the lowest price we've seen for the iPhone 5s. (It's also $149 below the best price we could find for a new one.) It features an Apple A7 processor, 4" 1136x640 Retina display, 8-megapixel iSight camera with 5-element lens with f/2.2 aperture, True Tone flash, and 1080p video capture with 30 fps video shooting (120 fps shooting at 720p slow motion playback), 1.2-megapixel FaceTime HD camera, Touch ID fingerprint reader built into the home button, M7 motion coprocessor, 802.11n wireless, Bluetooth 4.0, and dual microphones.

A $40 activation fee and a 90-day AT&T warranty applies.
