Just when we thought all would be made right again, though, Giesecke & Devrient — the German firm that made the world's first commercial SIMs back in 1991 — has debuted a new "nano-SIM" that trims about 30 percent of the size off the already tiny micro-SIM. Though it's thinner than both the standard SIM and the micro-SIM, G&D promises that reverse compatibility with older devices will still be ensured with an adapter — not a great solution, of course, but it's better than producing an entirely incompatible component.
