Proper Enabling of MultiTouch Code - JS

I thought this script below would enable multitouch as it iterates through the array of touches on each Update loop. I am told it does not do so on iPhone and do not have a recent device to test it on (I own the first version of the iPad and iPhone and they won't update..the iphone reset itself to 1978 or 1969). Can someone point out what it is that needs adjusting.

Code (JavaScript):

1. var useMouse : boolean;
2. var levelCtrl : LevelController;
3. function Start () {
4.  
5. }
6. function Update () {
7.     // Code for OnMouseDown in the iPhone. Unquote to test.
8.     var hit : RaycastHit;
9.     if (!useMouse) {
10.         for (var i = 0; i < Input.touchCount; ++i) {
11.             if (Input.GetTouch(i).phase == TouchPhase.Began) {
12.                 // Construct a ray from the current touch coordinates
13.                 var ray = camera.ScreenPointToRay (Input.GetTouch(i).position);
14.                 if (Physics.Raycast (ray,hit)) {
15.                     print (hit.transform.gameObject);
16.                     var hexagonName = hit.transform.gameObject.name;
17.                     levelCtrl.FlipTileToObverse (hexagonName);
18.                 }
19.                }
20.            }
21.     } else if (Input.GetMouseButtonDown(0) && useMouse) {
22.         ray = camera.ScreenPointToRay (Input.mousePosition);
23.         if (Physics.Raycast (ray,hit)) {
24.             //print (hit.transform.gameObject);
25.             hexagonName = hit.transform.gameObject.name;
26.             levelCtrl.FlipTileToObverse (hexagonName);
27.         }
28.     }
29. }

 

Thanks Graham. I presume multitouch code was correct then. My guess then is that the client did not set the useMouse flag to false and the mouseDown was giving him single touch capabilities only. I will implement the above suggestion which will avoid user error. How do you put #if ANDROID on the same line as #if UNITY_IPHONE, or do i have to replicate the for loop?
