    The << Softkey makes a browserlike back. But i want to be sure, that the user makes a Log Off.
    Is there any chance to override the << Hard Button on my phone that it executes a logout like...
        <Name><xsl:valueOf select="Log Off"/></Name>
        <URL><xsl:valueOf select="/@target"/>?_page_=LOGOUT</URL>
