The World’s Heaviest iPhone Case

You know how you see folks running or jogging and holding those pathetic little half-kilo (one-pound) dumbbells in their hands? And you know how sometimes you also see runners carrying their iPhones in a hand?

What if there was a product which was both a weight and an iPhone case? Somewhat predictably, given the title of this post, now there is. It’s the ToneFone, and it is billed as “The World’s Heaviest iPhone Case.”
