"Is that a scratch on your iPhone", a friend of mine asked, much to my horror and surprise. I'd only had this iPhone 3GS for a couple hours and already pesky scratches were beginning to show on its shiny plastic back. The glass back on my iPhone 4/4S has proved far less prone to wear and tear, perhaps partially due to past experiences which taught me to handle my pricey devices with utmost care.
You'd be pressed to think there was no difference in how black & slate and white & silver iPhone 5 models withstood wear and tear stemming from daily use. That said, you're in for a surprise as some folks apparently have discovered that both the anodized aluminum back and the chamfered edges of the black iPhone 5 are conspicuously more prone to wear versus its white counterpart...
