here it goes:

        foreach (TouchLocation tl in touchCollection)
        {
            if (tl.State == TouchLocationState.Pressed)
            {
                  ...on touch down code
            }

            if (tl.State == TouchLocationState.Released)
            {
                  ...on touch up code
            }
