My wife upgraded her iPhone 3 Pro Max so I inherited it. Up until a few days ago I’d been using my iPhone 8 Plus. Never had any problems with it and it’s age doesn’t effect it’s usability. The battery works but it’s beginning to swell (see photos) and at some point will need to be replaced. There’s a guy in Greenville that comes to your house (at least there was) and replaces the battery with a non Apple battery for $50, or you can have Apple do it for $89.00. The screen it flawless, I always had a screen protector on it (I believe I still have some I can give you). It comes with a cover that’s a wallet that holds all of your cards. I’ll consider trades as well. It is unlocked & cleared like new.
