once I had a iphone 3G for a year before I managed to smashed it when I were out dancin'... then I upgraded to a 4G two months later, beautiful. I'm to cool to have a cover on my iphone so four months later I dropped it on halloween, i was lucky. only the backside of the 4G were smashed. then i went out dancin' again, i like dancing a lot... after a few whiskey, on a crowed underground dance floor totally lost in the sound, I managed to drop the 4G again. This time a saw it in slow-motion how the display totally front and back were getting smashed! two weeks later I went to the apple store, a appointment in the genius bar, and minus £140 later I got a totally new 4G. good service. my 4G now have rubber on it, protected. It will not get dirty again.
