Apple compares the iPhone 4 glass to a helicopter windshield, and say its 30 times harder than plastic and less prone to breakage.
On its website, Apple talks up the "aluminosilicate glass" used in the iPhone 4, which it says is the same type of glass used in the windshields of helicopters and high-speed trains.
"Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever," Apple says.
A Sydney iPhone repair shop has seen different after the first broken model came through their door.
According to the Sydney repair shop, one must be careful not to drop their iPhone 4 because the cost to repair the glass is significantly higher than the 3G[S]. (I feel no matter what iPhone one owns one must be careful not to drop)
The young gentlemen that dropped his phone off at the Sydney repair shop states that it will cost $199.00 to repair and states that he feels the iPhone 4 was just as, if not more fragile as the previous models. For the 3G and 3Gs models a screen repair was around $129.00
Remember - Apple does not cover it if you drop it. The phone slipped out of his hands because he was carrying too many things. He also provided photos showing the damage on dropped iPhone 4 models follows a similar pattern of previous versions.
EDIT: The gentlemen stated "I kind of regret not putting the cover on straight away but I didn't think it would shatter like that, I just thought it would be a small scratch," he said.
"It's not even as durable as a BlackBerry - I drop the BlackBerry all the time but i've never seen something that's shattered this quick."
