I upgraded from 3GS to 4S. Then when the iPhone 5S came out, I bought a used iPhone 5 for cheap in order to get off the S cycle. A year later I upgraded to the 6.
When AT&T got rid of contracts and let current users upgrade early, I got the 6S and sold my 6. I plan on skipping the 7 and getting the 10th anniversary iPhone 8 model next year.
