I can't help but wonder exactly what it was that scratched the glass surfaces.
Got uncut diamonds in you pockets? <grin>
>> The highly scratch-resistant models are the 4 and the 4S, which use "Gorilla glass".
>> This is an alkali-aluminosilicate sheet glass engineered specifically to be thin, light and damage-resistant.
>>
>> Gorilla Glass hardness is comparable to that of sapphire, which is 9 on the Mohs scale of hardness. Regular glass is much softer, closer to a 7 on the Mohs scale. The increased hardness means you're less likely to scratch your phone or monitor from daily use or contact with other items in your pocket or purse.
