I think the puck is going in the direction of an ever increasing number of people who buy used iPhones. So I don't think that the iPhone 4 is going away soon.

I think the puck is going in the direction of an ever increasing number of people who buy used iPhones. So I don't think that the iPhone 4 is going away soon. Looking around, I see that a lot of people who can't afford (or don't want to afford) new iPhones are starting to buy used iPhones instead of cheap new phones.
