As one of its daily deals, with activation of a new 2-year contract, Best Buy offers the Apple iPhone 5s 16GB Smartphone for Sprint in Space Gray, Silver, or Gold for $49.99 with free shipping. That's a $8 drop from our August mention and the best outright offer we've seen for this iPhone on this carrier. (It's also a current price low by $28.) It sports 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.
