Is GlassGate the Latest Crack in the iPhone's Armor?
Sources both inside and outside of Apple told gdgt that the iPhone engineering team has been sent into "lockdown mode" by the issue. It's not just about scratching, but instead that the scratching can turn into cracking or fracturing of the entire rear pane of glass.
It sounds somewhat similar to what can happen to a windshield that has a chip. You can get a small chip from a rock, but sometimes the chip will spread, until a crack runs all the way across your windshield.
However, it's unclear if this is really as big a problem as gdgt says. After all, YouTube and the Web were flooded were flooded with complaints over the "death grip," with videos showing the problem, to boot. A search of Apple's support forum turns up a number of threads about cracked screens, but they don't seem to be related to cases.
Therefore, there isn't correlation there. Thing is, a post like this is liable to make people take careful look at their iPhone 4s, and cause an epidemic in and of itself. We'll see if the gdgt story creates cracks in Apple's armor.
