AT&T: Get iPhone 7 for $0 when you trade in an eligible iPhone

How to get your iPhone 7 32GB for $0**:

1. Buy the iPhone 7 or iPhone 7 Plus on AT&T Next® or AT&T Next Every YearSM and activate with qualified wireless service (starting at $50/mo. for new customers, or existing customers may add to an eligible plan). Pay tax at sale.
2. Make sure your current iPhone 6, iPhone 6 Plus, iPhone 6s, or iPhone 6s Plus is in good working condition and is paid in full.
3. We’ll send you a message with the information you need to complete your trade-in.
4. Once we’ve confirmed your purchase and received your trade-in, in up to 3 bill cycles we'll begin to apply your monthly bill credits. As long as you stay in good standing with eligible service on your installment agreement, you'll receive monthly credits totaling $650. That is equivalent to making an iPhone 7 32GB $0 or taking $650 off the price of the other variants or iPhone 7 Plus.
