Abstract

An interchangeable cover for a mobile communications device is provided. The interchangeable cover includes a a resilient three-sided semi-rigid shell having a substantially U-shaped profile adapted to wrap around a substantial portion of a front, back and side of the mobile communications device upon assembly over the device, without requiring any fasteners. In one embodiment, the cover is configured to fit a mobile communications device having a trapezoidal profile, whereby front and back face portions clasp around the front and back of the phone. In accordance with various embodiments, the cover may include holes and slots through which phone buttons pass, dumb buttons, or built-in buttons that enable users to provide inputs to the phone. The three-sided shell provides additional surface area when compared to conventional single-sided faceplates. Accordingly, the cover appears as a more integral part of the phone. Furthermore, the extra surface area may be used for advertisement purposes.
