A new report by iFixYouri suggests that although Apple claims the iPhone 4 glass is incredibly strong, it shatters very easily.
Apple says the glass is "chemically strengthened to be 30 times harder than plastic, more scratch resistant and more durable than ever."
iFixYouri notes that 95% of glass shattering is caused by shock and sudden impact rather than bending. They decided to put the glass to the test.
We have a full iPhone 4(minus the circuit board), here at our shop and decided to do a little drop test. This drop was performed from 3.5 ft up. Mind you that these parts ARE original apple parts. Laser etched and all. The iPhone 4 did survive 2 drops, as expected, but on the 3rd drop there was a loud POP, and yet again, shattered glass.
The site believes that the new design has flaw which contributes to this easy shattering. On the new iPhone, the glass basically sits on top of the aluminum frame. On the old iphone, it was recessed and protected by a chrome bezel.
This may be why Apple has announced its own official cases for the iPhone 4. These cases called "Bumpers" slip around the edge of your iPhone 4 and likely cushion the impact to the glass when dropped.
