PhoneGap plugins, why a different Javascript part for each platform (Android, iOS)?
var FilePlugin = function() {};
FilePlugin.prototype.read = function(data, successCallback, failureCallback) {
return PhoneGap.exec(
        successCallback,
        failureCallback,
        'FilePlugin',
        'read',
        [data]);
};
PhoneGap.addConstructor(function() {
PhoneGap.addPlugin("FilePlugin", new FilePlugin());
});
