The iPhone Duo on Amazon (paid link) arrived just this week and brings a foldable design that changes how the phone sits in hand, but it is priced at the flagship level and won't fit in your jeans. The iPhone SE (2nd gen) (paid link) still gets iOS updates, but because it runs the oldest supported chip it is probably next to lose them. If you want the latest tech, the Duo is the clear choice; if you need a phone that disappears in a pocket, the SE wins on practicality.
