4 (29)1. INTRODUCTIONThis Service Developer's Guide for the Nokia 6210 and the Nokia 6250 provides information andpractical examples for developers who want to develop WAP services for the Nokia 6210 and the Nokia6250. The document will highlight the possibilities, limitations and requirements of servicedevelopment and provides a good introduction to the Nokia style of designing user interfaces.Although the following chapters focus on the Nokia 6210 user interface, the guidelines can be appliedto the Nokia 6250 as the browser is basically the same in both phones.The Wireless Application Protocol (WAP) will enhance the functionality of mobile handsets throughreal-time interactive services. The protocol has been designed specially for small screens and lowbandwidth, and it offers a wide variety of wireless services over the Internet using handsets. In additionto Nokia 6210 and Nokia 6250 -specific issues, many of the instructions in this document can be usedto maximize interoperability and ease of use on various other browsers.This guide is not written for service developers only, but essentially for anyone involved in creating thewireless information society and anyone who needs to know more about service creation on smallmobile terminals. It can be used in conjunction with the Nokia WAP Toolkit.The Toolkit offers developers an environment for creating, testing and demonstrating WAP applications.This allows service providers to evaluate the usability of wireless applications and services togetherwith their end-user organization.We at Nokia are very proud of our user interfaces and we have put a lot of effort into constantlyimproving them. In this guide we have collected a lot of what we have learned to help developersimprove their services. We believe that good usability will increase use and satisfaction andsubsequently revenues for service providers.This guide is not intended to be a detailed WAP document and it is not meant to replace any WAPspecification.1.1 ReferencesUser's guide for the Nokia 6210User's guide for the Nokia 6250The Nokia WAP Toolkit can be downloaded from http://www.forum.nokia.com/Wireless Application Specifications http://www.wapforum.org/Information about Nokia products can be obtained from http://www.nokia.com/1.2 Contact informationDeveloper support can be obtained through Forum Nokia web-page http://www.forum.nokia.com/
