2. What You Should Already Know

The WAP Forum, now a part of the Open Mobile Alliance Ltd. (OMA), defined the Wireless Application Protocol (WAP) specification as a global standard for mobile Internet applications and browsing. The latest version of the specification, WAP 2.0, is XHTML MP. WAP specifications can be found on the WAP Forum Web site.

WAP developers who are already creating mobile Internet services using the Wireless Markup Language (WML) should understand the evolution from WML 1.x to XHTML Mobile Profile. For background information on the subject, developers can download the following two documents from the Documents section of the Forum Nokia Web site.

WML to XHTML Migration gives developers guidance on how to shift from WML to XHTML Mobile Profile.

Browsing on Mobile Devices provides an overview of WAP 2.0 technologies and describes the benefits of using XHTML MP and WAP CSS on mobile services.

3. What You Will Need

The Nokia Mobile Internet Toolkit 4.0 Starter Pack is an application development and testing environment for developers of mobile Internet content. It provides tools to create applications with XHTML MP, WAP CSS, WML, and WMLScript.

In addition to the Nokia Mobile Internet Toolkit, developers will need the Nokia 5100 SDK beta, which supports XHTML MP and WAP CSS and can be used to preview and test WAP applications.

5. Where to Go Next

Once you understand the basics of XHTML, it is time to think about the look and feel of the XHTML application.

The Nokia Mobile Internet Toolkit includes a document called XHTML Guidelines, which provides comprehensive information about creating content for mobile devices supporting XHTML MP and WAP CSS. For further information on the subject, Nokia also provides the following documents, which are available for download from the Documents section of the Forum Nokia Web site.

WAP Service Developer's Guide for Nokia Series 30 Phones with XHTML Browser provides information and practical examples on how to optimize mobile services for Nokia devices with a specific user interface.

Nokia GSM WAP Phone Characteristics document contains detailed information about the browser characteristics of Nokia devices. It lists features such as screen size, supported image formats, user agent name, and cache and deck size, among many others.

Nokia GSM WAP Phone MIME Types document lists the MIME content types currently supported on the browser of Nokia WAP phones. MIME types illustrate which content types can be downloaded through the browser to the phone.

Nokia GSM WAP Phone WML and XHTML Elements document describes the WML and XHTML elements that are supported on the browser of Nokia WAP phones.
