Abstract: The present invention provides a mobile device ecosystem that is simpler than existing options for all of its participants regardless of their role or business model. The ecosystem includes a mobile device and operating software development kit and store, both of which are implemented as web-based services such that creation, testing, and distribution of customized mobile devices, as well as discovery, investigation, and delivery of same, can all be performed using a standard web browser. The device development kit offers such capabilities as simply personalizing the exterior decoration of an existing device, designing the physical form factor of a device incorporating existing electronic components, and even creating new electronic components for incorporation in multiple device designs.
