With a new 2-year agreement, Walmart retail stores discount the Apple iPhone 5 16GB Smartphone for Verizon in Black or White to $129. (Note that the link is for reference only; it can't be purchased online. Also, Sprint offers its model for $99.99 with free shipping.) That's tied with our mention from two weeks ago and the lowest price we could find by $70. It features an Apple A6 processor, 326-ppi (pixel per inch) Retina 4" display running at 640x1136, front- and rear-facing cameras, 8-megapixel camera with LED flash, 1080p video capture at 30 fps, 802.11n dual-band wireless networking, 1GB RAM, and dual microphones.

Walmart retail stores also offer the Apple iPhone 4S 16GB Smartphone for AT&T or Verizon in Black or White for $39. (Sprint has it for free with free shipping.) That's also tied with our mention from two weeks ago and another low for this phone on both networks, this time by $60. The iPhone 4S is powered by the Apple A5 dual-core processor and features an 8-megapixel camera which is capable of recording 1080p video at 30 fps with image stabilization. A dual-antenna system has also been added, which purportedly provides faster downloads and improved call quality on both CDMA and GSM networks. It also features AirPlay Mirroring, Siri voice-activated assistant, and an 8-hour battery life.
