A cover for an electronic device having a first panel including a first and second edge, a second panel including a first and second edge and being positioned adjacent the first panel, a third panel including a first edge adjacent the second panel opposite the first panel, and means for connecting the first panel to a device holder or to the device itself. The cover may attach to a separate back panel which can be detachably secured to the electronic device. The second edge of the first panel, the first and second edges of the second panel and the first edge of the third panel are slanted so as to allow adjacent panels to be configured to form an angle to one another. The edges of adjacent panels are V-shaped and include two sidewalls which abut when the panels move together. This limits the minimum angle between adjacent panels.
