XML Browser
XML browser simply means that the phone screen display can be managed by external applications. The XML
browser feature allows users to develop and deploy custom services which meet user’s functional requirements on
the server. Users can customize practical applications, such as weather report, stock information, Google search,
news service, and so on.
To use the XML browser feature, you must configure an XML browser key in advance.
