With activation of a new 2-year contract, AT&T Wireless offers an Apple 8GB iPhone 4s in White bundled with a $100 Bill Credit for free with free shipping. (Verizon Wireless has it in White or Black for the same deal; however, they charge an activation fee of $35.) That tied with last week's mention as the best such deal we've seen on this phone for either Verizon or AT&T.
Of note, the credit will be applied to your account within 2 to 3 billing cycles.
With activation of a new 2-year contract, Verizon Wireless offers the Apple iPhone 5c 16GB Smartphone for Verizon in White bundled with a $100 Verizon Wireless Credit for $99.99 with free shipping. Assuming you'll use the credit, that's tied with our mention from yesterday as the lowest total price we've seen for the iPhone 5c. (It's a current price low by $50 after factoring in the credit.) It features an Apple A6 processor, 4" 1136x640 Retina display, 8-megapixel iSight camera, 1.2-megapixel FaceTime HD camera, 1080p video capture, 802.11n wireless, Bluetooth 4.0, and dual microphones.
Note: It's currently on backorder, with an estimated ship date of March 6.
