i think iphone updating too fast i prefer to stay with same phone for years not to change every minute :) and new phones dont have much more functions than olds, only sometimes in terms of videocamera.
and ye 1000$ is not worth it if u have any other iphone or modern samsung.
I have kind of the same thoughts! People are selling their one-year old phones in order to buy the newest version/generation. It often haven't got so many new features and I believe technology is running fast. Wait one year longer or two and you will be blown away !
