"Error: Calling parameters do not match signature" when using ajax-jquery in iphone web app

Question

In creating a iphone web app, i used magento XML RPCto call magento web services. With the help of jQuery XML RPC i can access the magento web services.My code,

<script src="js/jquery.mobile-1.2.0.min.js"></script>
<script src="js/jquery-1.8.3.min.js"></script>
<link rel="stylesheet" href="css/jquery.mobile-1.2.0.min.css"></link>
<script src="js/jquery.xmlrpc.js"></script>

<script>
$(function(){
$("button").click(function(){
   $.xmlrpc({
          url:"link of my magento/xmlrpc",
          methodName:'login',
          params:['user','pass'],
          success: function(response, status, jqXHR) {
                  var res=response;
                  alert(res); // getting alert as session id as login response
             $.xmlrpc({
                       url:"link of my magento/xmlrpc",
                       methodName:'call',

               //passing session id from the previous response
                       params:{sessionId:res,methodName:'customer.info',customerId:'3'},
                       success: function(response1, status1, jqXHR1) {alert("success:"+response1);},
                       error: function(jqXHR1, status1, error1) {alert(error1); }
                   });
                },
            error: function(jqXHR, status, error) {alert(error); }
         });
     });
 });

</script>

Here my problem is, when i run the app i get the session id and pass the id to next method "call" with the parameters.This code while executing gives me an error stating "Error: Calling parameters do not match signature"

I changed the way of passing parameters too but no hope. Can anyone suggest me how to solve this problem.

I believe this is a bug.

Take a look at this thread: Calling parameters do not match signature
