As I see it the S cycle upgraders are getting the better deal. The S models are the refined version of the generation. Either way though, if you change iPhones every 2 years, you're fine, no one is getting screwed.
Very true. I have the 4s and personally the 5 has not that great of updates to make me want it. I will get the 5s and if the 6 is a lot better and bigger screen ill sell my 5s and buy it full price if it is truly a big improvement over the 5s. As I see it the S users get a good phone it's just preference and its not hard to get out of the S cycle
