If you're feeling nostalgic for tactile keys, a conceptual iPhone case transforms your touchscreen into an old-school keypad.

Designer Moon Myounghak has created a case that features a physical set of keys, alongside a touchscreen that spans five icons across, according to website Yanko Design.

In order for the custom keyboard to be functional, however, the iPhone would have to be hacked. There's no word yet on when the concept will become real. In the meantime, those missing the ability to click can always opt for a BlackBerry.
