Two fingers orbit camera?

Hi guys, I’ ve been working for some time with this wonderful script writing by Randal J. Phillips, but now I want to make just only same orbit camera gesture but with 2 fingers in mobile devices. I am newbie so I really appreciate so much your help.
any example?, thanks for sharing!
this is the famous sript:

/*
Touch Orbit
Programmed by: Randal J. Phillips (Caliber Mengsk)
Original Creation Date: 12/16/2011
Last Updated:                   12/16/2011
Desctiption:
        Simple orbit by one touch and drag, as well as pinch to zoom with two fingers.

private var gameCamera:Camera;
function Start ()
{
        gameCamera = Camera.main;
}
function Update ()
{
        if (Input.GetKeyDown(KeyCode.Escape))
        {
                Application.Quit();
        }
      
        if (Input.touchCount == 1 && Input.GetTouch(0).phase == TouchPhase.Moved)
        {
                //One finger touch does orbit
                touch = Input.GetTouch(0);
                x += touch.deltaPosition.x * xSpeed * 0.02;
                y -= touch.deltaPosition.y * ySpeed * 0.02;
        }
        if (Input.touchCount > 1 && (Input.GetTouch(0).phase == TouchPhase.Moved || Input.GetTouch(1).phase == TouchPhase.Moved))
        {
                //Two finger touch does pinch to zoom
                var touch1 = Input.GetTouch(0);
                var touch2 = Input.GetTouch(1);
                curDist = Vector2.Distance(touch1.position, touch2.position);
                if(curDist > lastDist)
                {
                        distance += Vector2.Distance(touch1.deltaPosition, touch2.deltaPosition)*pinchSpeed/10;
                }else{
                        distance -= Vector2.Distance(touch1.deltaPosition, touch2.deltaPosition)*pinchSpeed/10;
                }
                lastDist = curDist;
        }
      
        if(distance <= minimumDistance)
        {
                //minimum camera distance
                distance = minimumDistance;
        }
      
        if(distance >= maximumDistance)
        {
                //maximum camera distance
                distance = maximumDistance;
        }
      
      
        //Sets rotation
        var rotation = Quaternion.Euler(y, x, 0);
      
        //Sets zoom
        var position = rotation * Vector3(0.0, 0.0, -distance) + Vector3(0,0,0);
      
        //Applies rotation and position
        transform.rotation = rotation;
        transform.position = position;
}

Hi, I’ve looking in other options and then I came back to the original script & just make a little change in the line of count
from this:

 if (Input.touchCount > 1 && (Input.GetTouch(0).phase == TouchPhase.Moved || Input.GetTouch(1).phase == TouchPhase.Moved))

to this:

 if (Input.touchCount > 2 && (Input.GetTouch(0).phase == TouchPhase.Moved || Input.GetTouch(1).phase == TouchPhase.Moved))

& it works now!
