[SOLVED] How to integrate Juggernaut chat server (Powered by ruby on rails) with iPhone/Android app for real time chat?

How to integrate Juggernaut chat server (Powered by ruby on rails) with iPhone/Android app for real time chat?

Preview:

I am using juggernaut chat server.I am having redis and juggernaut server running on machine. I am able to do chats within my local network on vaious web browsers. Everything is working smoothly. As juggernaut is a server driven chat server so i am quite sure about the scalability thing. Now here is the thing:--

Whats the problem:

I want to have a iphone native app too where user can login and chat with his friends. Now the thing i want to know is how do I push on iphone app, cause for juggernaut client registration a javascript code is needed. Something like this:

          var jug = new Juggernaut;
      jug.subscribe("channel1", function(data){
        alert(data);
      });

Basically how do i push new notifications to Iphone chat window. I don't know much about iphone as I am web developer. Still from google search etc I came to know some possible ( may be) ways:-

We can embed a url in iphone window. Is this a good approach?
Other thing we can do is using UrbanAirship kind of services we can do push notifications. Will push notification works for chat? I don't know about that even.
Third option can be polling. Iphone chat client keeps on hitting my rails app for new notifications. But i think this will be a very bad approach.

What are the other possible solutions?

Can any iPhone/Android developer guide me what should i do. I will eventually hire a Iphone developer to do all the coding part. But I want to have a big picture in my mind so that I can provide a complete docs of all the things, and have a clear picture how I want to discuss things with him before writing down the code.

PS: I am looking for a solution which works for android/nokia devices too. Cause later on I will be developing an application for that too. Basically it will be good to have a same solution. if not then compatibility factor should be there atleast.
