This happened to me. I re-upped for two years last year with the 5s. But I am eligible this year. The reason is because AT&T is *hot* to get everyone off their grandfathered Family Plans with unlimited data onto monthly-data plans under their new "Mobile Share" packages. With some folks (like me), if your data usage is in-line, the new plans can save a lot of money. You lose unlimited, but if you log in and look at your past usage, you probably use less than you think. So, they are offering upgrades this year, one-year in. Works for me.
