Platform	S60 5th Edition	Tested on devices	Nokia 5800 XpressMusic
Category	Web Runtime (WRT)	Subcategory	PIM

Keywords (APIs, classes, methods, functions): device.getServiceObject(), Service.Contact.Add()

Overview

This code snippet shows how to add contacts to the device's default phone book using the Contact Platform Service for S60 Web Runtime introduced in S60 5th Edition.

To obtain access to the service object for the Contact Service API, the device.getServiceObject("Service.Contact", "IDataSource") method is used.

After setting the correct values for the criteria object (criteria.Type and criteria.Data), the IDataSource.Add(criteria) method is used to add the new contact.
