Greetings all, Just thought I'd share my positive experience regarding my iPhone. While I'm not so fond of Apple in the recent years I have always admired the excellent support they provide and the people working to make us all happy. Now recently my iPhone kept displaying this "This accessory is not optimized for iPhone" error which would cut off the audio until I either plugged in a dock connector or restarted the phone. I checked the bottom sensor which was indeed red but I had never taken the thing near water, or even in the bathroom. So I went to the Regent Street store (even for such a busy store I was able to book an appointment the same day) and told them honestly that I had never put the thing in water. I've had bad experiences with my old iPod touch when it lost its wifi capability and they claimed it was due to water damage so I was sceptical when the lady at the genius bar shone a light at the dock connector. She spoke to her manager who said that it is possible for the sensor to be triggered randomly and the dock connector could indeed have been compromised by lint or even a tiny drop of water so they replaced it for me there and then. But here's the amazing part - after leaving the store I look at my new iPhone only to realise they've given me a 32GB instead of a 16GB. Honestly it was tempting to just keep it but they had given such great service I actually felt rather guilty, so I returned to the genuis bar, and you know what? They let me keep it. I have to say I can never imagine any other company doing that, thanks Apple.
