I could not imagine my life without my iPhone 4. It does absolutely everything, and then some!
I previously had a 3G, and it feels so primitive to use it now compared to the 4.
Only minor issue I had with it was that the battery randomly heated up one day to the point that I couldn't touch the phone - I took it into Apple and they couldn't see why it had happened, and they said that the phone was fine. It hasn't happened again since, and it certainly hasn't changed my view of the iPhone 4. Its amazing performance day-to-day negates any small issues that the phone may I have, in my opinion.
