The device object is supported since WRT
+1.1.
The device object is a built-in JavaScript object
+in the widget engine. It was introduced in WRT 1.1 to allow widgets access
+to S60 Platform Services through Service APIs. The device object
+is used to create service objects for specific Service APIs. These service
+objects can then be used to access the services made available through the
+Service APIs.
The device object can be accessed simply via device.
+In the WRT environment, the term device is a reserved
+keyword and should not be used as a user-defined global variable name for
+other type of objects.
