The purpose of this site is to provide information to people interested in the Jitterbug phone, by Samsung (SPH-A120). The Jitterbug service and concept come from Great Call Inc., with the founders being Marty Cooper and Arlene Harris.  

Martin Cooper is said to be the father of personal mobile communications, in other words cell phones. Remember those big brick like cell phones? The ones that could only run for 30 minutes on a full charge, the ones that cost $4000 at the time back in 1983? Those original cell phones were because of Marty. Car phones were already in existence, briefcase sized and hidden in the trunks with a wire that ran to a large house phone sized set in the front of the car. But Marty shrunk all of that down into a handset and now just about everyone has a mobile phone.
