I had a case of misdiagnosis with the sensor on my iPhone 3G, went to Regent Street to see a Genius because my Wifi wasn't working, Said it was Liquid Damaged, and they couldn't do anything about it. Went home extremely angry and upset because I didn't expose it near Water, don't take it to the Bathroom etc.
Got home, called up Applecare who linked me to the Liquid Damage page as above, I checked the sensors myself are they were both White as can be. Went back another day and spoke to another Genius who replaced my iPhone and the other 'Genius' doesn't work there anymore.
Anyway, as countless others have pointed out - Apple's sensors are shocking and their policy should be nothing like this, although others have reported that it will go back to White after a few days sometimes (Moisture?).
Anyway Good Luck and let us know what they say, speak to a Manager if the Genius refuses to offer you a replacement. Don't be angry with them, as it's Apple's policy and they don't make the rules, if you talk calmly with them they will probably offer you a replacement.
