Hello, I have recently had the misfortune to crack my iPhone 4 screen. I have heard various rumours such as "Take it to an apple store and if you are still under warranty and haven't broken your screen before they will replace it for you 1 time for free." - Is this true? - If it is, what are the best techniques and social engineering to make make sure you get the new replacement (What are the best excuses) If not, can some one please explain the cost and were I would have to go to get apple to repair my screen within warranty? Thanks.
