I went from an iPhone 4 to a 5 didn't want to upgrade when the 4s came out cause I didn't see any good reason to and Siri wasn't good reason for me to ditch the iPhone 4. Now with that said when the iPhone 5 was announced I upgraded. And for me this was a major upgrade. And when I found out that AT&T had just deployed LTE where i live, well let's just say that was a bonus lol.
