I dropped my iPhone 4 and the screen smashed, went to apple was honest about what happened and they said to me "you mean your phone has a fault in the glass sir" I was a little confused and said yes I guess so, the genius then replied " oh, well in that case we can replace the unit for you" and have me a newly refurbished phone (these look brand new l, but come in cardboard packets) might be worth booking a genius appointment and pop in to an apple store.
