I have a 4S that slipped from my pant pocket onto a rough concrete floor from sitting height. The rough surface dented the plastic trim, causing the glass to shatter. I believe they went with the plastic trim due to the problems of joining glass and metal. But the plastic trim is the iPhone 4's Achilles' heel.
In any case, IIRC, speculation is that only the screen side of the iPhone uses Gorilla glass, but I'm not sure if that's changed with recent generations. But even without Gorilla glass, you can still use "standard" toughened glass that, correctly mounted, should never shatter just from the sort of thermal shock described in the article.
