System access and copy protection
Applications developed for distribution on the Android Market allow the developer to enable copy protection which prevents the end user from copying the application from the phone. Because the Android Dev Phone allows unrestricted access to the OS, this copy protection is disabled. If the developer enables copy protection on their application, then the application does not appear on the Android Market for the Dev Phone.Availability
