I did one about 10years ago using an old phone I got at a garage sale. I was going to copy the Sparkfun design but instead I made mine a Bluetooth one so that you don't have to tied up a cellular line. Anyhow, at the time I was working at a wireless company and I made up a fake collateral sheet for it on April 1st and circulated it around. Everyone thought that was the joke, but then I showed around the actual phone that you could make and receive calls on and it blew everyone away. It was really funny because for about a minute the marketing department thought about productizing it for real ! Anyway, nice work on your version! very cute :)
