I own an iPhone 4, my first. I fell in love with the iPhone while waiting in line for 10 hours with my daughter on release day. We got to know the people in line with us so well, that they promised to name their first born after us!
They also did a very good sales job on the phone, and it got me to thinking, and a month later I bought one for myself.
In retrospect I wish I would have upgraded in the fall to the 5, and then sold my 4. I probably would have made a little money. But I'm almost certain I will upgrade to the 5s this fall, still sell my 4, but of course the price will have dropped by then, and then renew every two years. I think if I do that I will essentially have a free phone.
