Well, since my iPhone 3g's ringer switch broke off yesterday, I had to go to the Apple store to get a replacement. Although I was made about something going wrong already, the manager himself switched it out in 5 minutes, no problem, and then offered up any of his employees to help out the other people in my party in front of anyone who was waiting. So a bad experience turned into a good one. My question for you guys is: Have you had to swap out your new phone because of any defects?
