Walmart offers the refurbished iPhone 4S 8GB for Straight Talk
in White, model no. A1387, bundled with a $45 30-day Straight Talk unlimited plan
with free shipping
. Including the plan, that's $25 under our September mention of the phone by itself and $5 under the lowest total price we could find for this phone with the same plan purchased separately elsewhere. It features a 3.5" 960x640 retina display, 8-megapixel rear camera, front camera, 1080p HD video recording, Bluetooth, WiFi, and iOS 7.
A 90-day warranty applies, although it's unclear who supports it.
