AT&T offers preorders of the Apple iPhone 7 32GB Smartphone for free with the trade-in of an eligible iPhone 6. (You must also sign up for an AT&T Next plan with qualifying wireless service.) That's tied with yesterday's T-Mobile offer (still active) and only the second offer we've seen for the iPhone 7, which was revealed September 7. These new smartphones are water- and dust-resistant and feature a new A10 Fusion quad-core processor, "Taptic" force-sensitive home button, and 7-megapixel FaceTime HD camera. Click here for full details of the phone's features. Deal ends September 30.

Note: The retail price is divided into monthly installments, and the phone is free after $650 in monthly bill credits ($21.67 or $27.09 per month, depending on which AT&T Next plan you choose). The credits may take up to three months to appear on your bill, but you will be credited retroactively for the intervening time.
