Just answer a few questions online or in an Apple Store regarding the condition of your iPhone. We’ll provide either an estimated trade-in value or a simple way to recycle it if it’s not eligible for credit. If you’re trading in online, we’ll apply your estimated trade-in value to the purchase of your new iPhone. We’ll then send you a trade-in kit (at no cost to you) so you can send us your device. Once we’ve received your trade-in device, a team will inspect it and verify its condition. If the condition matches what you described, there’s nothing more you need to do. If it doesn’t match, your original payment method will be charged the difference in value. In that case, we’ll work with you to confirm that you still want to move forward with the trade-in. If you accept the trade-in estimate in the store, we’ll give you instant credit towards a purchase.
