What are options for owners of IPhone SE as 5G becomes more available. Mine is a relatively new phone, still under warranty/insured. Will Apple Store offer some amount as a buy back when buying a newer model?

Be sure 5G is enough reason for-the-moment. Some people report spotty 5G coverage currently in their area, other report complete-uninterrupted 5G coverage. Is the money worth spending now for the areas you will use it? Only you can answer that.
