This Javascript sends OnMouseDown messages based on iPhone taps, so you can use OnMouseDown callbacks. Attach the script to the camera that is rendering the clickable (tappable) objects. Add a layer argument to the Raycast call if you need to avoid unnecessary intersections. A similar script can be implemented for OnMouseUp (an exercise for the reader). This is only for 3D objects with colliders (e.g. this is used for the 3D menus in HyperBowl), not for GUIText and GUITexture.

Spin Off: OnTouch

This script sends OnMouseDown messages based on taps, so you can use OnMouseDown callbacks. Attach the script to the camera that is rendering the clickable (tappable) objects. Add a layer argument to the Raycast call if you need to avoid unnecessary intersections. A similar script can be implemented for OnMouseUp (an exercise for the reader). This is only for 3D objects with colliders (e.g. this is used for the 3D menus in HyperBowl), not for GUIText and GUITexture.

[edit] C Sharp (C#) Script 

using UnityEngine;
 
/// <summary>
//	Allows "OnMouseDown()" events to work on touch devices.
/// </summary>
public class MouseDownTouch : MonoBehaviour
{
    private void Update ()
    {
        var hit = new RaycastHit ();
 
        for (int i = 0; i < Input.touchCount; ++i)
        {
            if (Input.GetTouch (i).phase.Equals (TouchPhase.Began))
            {
                // Construct a ray from the current touch coordinates.
                Ray ray = Camera.main.ScreenPointToRay (Input.GetTouch (i).position);
 
                if (Physics.Raycast (ray, out hit))
                {
                    hit.transform.gameObject.SendMessage ("OnMouseDown");
                }
            }
        }
    }
}

[edit] UnityScript / JavaScript 

function Update () {
   var hit : RaycastHit;
   for (var i = 0; i < iPhoneInput.touchCount; ++i) {
      if (iPhoneInput.GetTouch(i).phase == iPhoneTouchPhase.Began) {
      // Construct a ray from the current touch coordinates
      var ray = camera.ScreenPointToRay (iPhoneInput.GetTouch(i).position);
      if (Physics.Raycast (ray,hit)) {
         hit.transform.gameObject.SendMessage("OnMouseDown");
      }
   }
   }
}
