From the Toys section:

Starting December 18, Walmart retail stores will offer the Apple iPhone 4 16GB Smartphone for AT&T Wireless bundled with a $50 Walmart Gift Card for $197 with activation of a new 2-year plan. (This offer will not be available online.) Provided you use the credit, it’s the best price we’ve seen on this phone, outside of promotion from RadioShack two weeks ago. (RadioShack stores offered this model for as low as $24 upon trading in an older iPhone, since expired.) Sales tax is added where applicable. It features an Apple A4 processor, 326-ppi (pixel per inch) Retina 3.5″ display running at 960×640, gyroscope, front- and rear-facing cameras, 5-megapixel camera with LED flash, 720p video capture at 30 fps, 802.11n wireless networking, dual microphones, and more.
