No such luck. Brace yourself for "GlassGate."
Now, we all know that the i4's Gorilla Glass front and back don't live up to the hype when it comes to scratch-resistance, much less shatter-resistance. (No less than English movie star/geek icon Simon Pegg suffered a fractured iPhone back in July…) But the latest wave of glass fails actually appear to be Apple's (un)doing.
Here's what's been happening: Post-AntennaGate, the House of Jobs has been on the warpath to get every i4 owner to obtain a case for their phone. Interestingly, if you go into an Apple Store, the only cases you'll find are the so-called bumper cases. That's because Apple gets a cut of the casemaker's profits in return for prominently featuring said cases in their retail outlets.
But there's another, more seditious reason non-bumper cases aren't "Apple approved." It appears that certain third-party cases — specifically, those that slide on — can catch particulate matter that will scratch the glass case. Said scratching can easily develop into full-blown cracking, or even a complete shattering of the back glass, through no fault of the user.
Apple engineers have reportedly locked themselves into a room to solve this latest problem. The most logical solution, of course, would be to return to the metal cases of older iDevice models.
