if ( Browser.ie && Browser.version == 7 && Browser.Platform.other ) {
// whatever
}May work, don't know I don't have a windows phone (I hear there are only like 50 in existence anyway) :-)
If this does not work then try writing a simple html page that does
alert( 'Browser: ' + Browser.name + '\n' +
'Platform: ' + Browser.Platform.name + '\n' +
'Version: ' + Browser.version );
Then use those values in your if statement.
