iPad touch is offset! Unity2d.

Hi Everyone, My game was working fine until I upgraded to Unity 4.5.1. I have code that simply detects if an object is touched.
It works in the Unity Game window, it works on Android, but for some reason, the x value on the iPad is offset by 10 (after screentoworldpoint is run).

Is there a reason why upgrading Unity would change this? Was I doing it wrong to begin with? Either way, does anyone have any ideas on how to fix this?

Thanks, -Will

 public int hasTouchedObject(GameObject objectToCheck)
     {
         //Debug.Log ("Camera Location: x: " + GameObject.Find("Main Camera").transform.position.x + ": y: " + GameObject.Find("Main Camera").transform.position.x + ": z: " + GameObject.Find("Main Camera").transform.position.z);
         setTouches();
         for (int x = 0; x < touchList.Count; x++)
         {
             Touch thisTouch = touchList[x];
             //string touchphase = thisTouch.phase.ToString();
             if (thisTouch.phase == TouchPhase.Began) 
             {
                 Debug.Log ("touch x: " + thisTouch.position.x + " touch y: " + thisTouch.position.x);

                     }
                 }
             }
