A mobile communication device comprising: both a first member and a second member, - the first member having a first surface with a first radius of curvature, and a second surface with a second radius of curvature; - the second member having a third surface with a third radius of curvature, and a fourth surface with a fourth radius of curvature; a hinge pivotally connecting ends of the first and the second members with one another to facilitate pivotable movement of the first and the second members between an opened configuration and a closed configuration; the communication device being characterized by a first display screen located on the second surface of the first member and a second display screen located on the third surface of the second member; the first radius of curvature and the second radius of curvature of the first member combine with one another to form a first average radius of curvature for the first member, and the third radius of curvature and the fourth radius of curvature of the second member combine with one another to form a second average radius of curvature for the second member; when the communication device is pivoted into the closed configuration, the first average radius of curvature for the first member and the second average radius of curvature for the second member form a device average radius of curvature for the communication device of between 5.08 cm "2 inches" and 243.8 cm "8 feet" to facilitate carrying of the communication device in a hip pocket of a user; the fourth radius of curvature is larger than each of the first radius of curvature, the second radius of curvature, and the third radius of curvature. both a first member and a second member, - the first member having a first surface with a first radius of curvature, and a second surface with a second radius of curvature; - the second member having a third surface with a third radius of curvature, and a fourth surface with a fourth radius of curvature; - the first member having a first surface with a first radius of curvature, and a second surface with a second radius of curvature; - the second member having a third surface with a third radius of curvature, and a fourth surface with a fourth radius of curvature; a hinge pivotally connecting ends of the first and the second members with one another to facilitate pivotable movement of the first and the second members between an opened configuration and a closed configuration; the communication device being characterized by a first display screen located on the second surface of the first member and a second display screen located on the third surface of the second member; the first radius of curvature and the second radius of curvature of the first member combine with one another to form a first average radius of curvature for the first member, and the third radius of curvature and the fourth radius of curvature of the second member combine with one another to form a second average radius of curvature for the second member; when the communication device is pivoted into the closed configuration, the first average radius of curvature for the first member and the second average radius of curvature for the second member form a device average radius of curvature for the communication device of between 5.08 cm "2 inches" and 243.8 cm "8 feet" to facilitate carrying of the communication device in a hip pocket of a user; the fourth radius of curvature is larger than each of the first radius of curvature, the second radius of curvature, and the third radius of curvature.
