iPhone input multitouch

Hello

I am having some problems with using GUITextures for input on the iPhone.

I have 3 GuiTextures - Left Movement / Right Movement / Fire

I have a script attached to the player controller. All of the buttons work individually, but I can't move and shoot at the same time. Here is the code I'm using to detect input on the three buttons:

function Update () { for (var i = 0; i < Input.touchCount; ++i) { var evt : Touch = Input.GetTouch(i); var myLeftHitTest = ArrowLeft.HitTest(Input.mousePosition); var myRightHitTest = ArrowRight.HitTest(Input.mousePosition); var FireTest = Fire.HitTest(Input.mousePosition);

   if (evt.phase == TouchPhase.Stationary) 
   {    
             if(myLeftHitTest) 
            {    
                 //Move player left  

            }           
             if(myRightHitTest) 
            {  
                     //Move player right
            }  
   }
   if(evt.phase == TouchPhase.Began)
   {
   if(FireTest)
   {     
       //instantiate bullet
       }
    }

}
}

Any help would be greatly appreciated!

Thanks
