It sure is. There are plenty of people who want an iPhone but can't afford and/or simply don't need/want the latest, greatest version (being able to run 11.0.1 isn't really a big concern for most of them). A good friend of mine just upgraded to an iPhone 4 a few months ago. Pretty much all Apple products have excellent resale value (around here, anyways).
