New and existing Verizon customers who trade in any iPhone in any condition can take up to $1,000 off a new Apple iPhone 15 when they pre-order the phone with a new smartphone line and an Unlimited plan. This is the best deal we found for the new iPhone 15, since the trade-in credits you'll receive will cover the full cost of the phone regardless of which model you choose. Pre-orders will ship for free starting on 9/22.
