Fantastic! My iPhone 4 warranty expired yesterday, the same day I went to my nearest Apple store with some problems relating to my iPhone 4. It had a dead pixel and the home button was unresponsive. I'd been planning to go to the store but hadn't had the time, and thought I'd give it a try since it was my last day on the warranty. I was told that because its the last day, I technically was out of warranty, so as you can imagine I got a little worried. No problem though, I was given a brand new iPhone 4! Seriously, I can honestly say that I've never had a bad experience in an Apple Store and I wish other companies followed Apple's example.
