Getting strings from WWW

Hey so I'm currently working on a unity project where Unity needs to constantly check for a new string from a website using WWW. As of now I created a script that adds and destroys a component based on whether or not the component has finished loading the webpage and reading the text. Does anyone have any cleaner ways of making a Android phone communicate with unity to send simple strings? heres my code at the moment

 //for Very early testing
 var card:GameObject;
 
 var currentCard:String;
 var places: GameObject[];
 var getCard: GetInfo; 
 var controller:P1Controller;
 var done:boolean = false;
 
 
 function Start () {
 
     //gets Main controller
     controller = this.gameObject.GetComponent(P1Controller);
     //sets card locations
     places = controller.getPlaces();
     //set current card to main controllers car
     currentCard = controller.card;
     //create a new check for a string
     getCard = this.gameObject.AddComponent(GetInfo);
     //load card for testing purposes
     card = AssetDatabase.LoadAssetAtPath("Assets/Prefabs/Tank.prefab", GameObject);
     //wait for WWW request to finish
     while(!getCard.isDone())
     {
         yield WaitForSeconds (.1);
     }
     //set card text and delete request object
     currentCard = getCard.getText();
     Destroy(this.gameObject.GetComponent(GetInfo));
     done = true;
 }
 
 function Update () {
     if(done)
     {
         if(getCard.isDone())
         {    
             //Destroy Object just in case
             Destroy(this.gameObject.GetComponent(GetInfo));
             if(currentCard == controller.card)
             {
                 //if cards are equal check again for changes
                 CheckAgain();
             }
             else
             {
                 //create new object test
                 Instantiate(card, places[2].transform.position, places[2].transform.rotation);
                 controller.card = currentCard;
             }
         }
     }
 }
 
 function CheckAgain()
 {
     //create a new check for a string
     getCard = this.gameObject.AddComponent(GetInfo);
     //wait for WWW request to finish
     while(!getCard.isDone())
     {
         yield WaitForSeconds (.1);
     }
     //set card text and delete request object
     currentCard = getCard.getText();
     Destroy(this.gameObject.GetComponent(GetInfo));
     Debug.Log("YOPP");
 
 }

thanks all
