Starscream122: And if it’s a phone that they no longer make new? I.e do you get a free upgrade to the oldest model still being sold?
It would be a re-manufactured iPhone of the exact same model, storage, and colour as your old one.
You can't upgrade or change colour in the replacement process, it's a like for like exchange only.
Apple still do replacements all the way back to the iphone 4s, so replacement for even old models isn't a problem.
