256GB I have an iPhone 17 Pro for exchange with an iPhone Air, with me paying the difference. Or exchange with an iPhone Pro Max, and I will pay the difference. The important thing is a bigger screen. Whoever is interested, please contact me. The device has protection since I first opened it from the box until today, and it has no scratches, and everything in it is sound and has no issues. The purpose of the exchange is solely that I want a bigger screen. Storage Capacity: 256GB Condition: Used
