Dear all My first iPhone had light leak, second had a chipped corner and the third started developing cracks around the headphone jack. Today a genius at the local Apple Store replaced the third for the now fourth iPhone. However, this visit was a little different in that he took a look down the headphone port and looked around the adapter area with a lit magnifying device (similar to what doctors use to look in your ear). He then asked the following questions: - Have you dropped the iPhone? - Where do you carry it: front pocket, back pocket, bag? - Do you use a case and which one? There may have been another question but I don't remember. Anyone else been asked these questions? The new phone seems OK, apart from a stuck pixel, which I can live with - and also I am led to believe I can 'unstick' (if anyone can help with advice here please do). I am a little worried about cracks appearing but the genius did say if you have any problems with that one bring it back and they'd swap it out again! I have to say Apple have been brilliant to me all the way through this! Cheers!
