  Since the end of the 2005-2006 austral summer, the IceCube detector consists
of an array of 9 strings, deployed between 1450 m and 2450 m of depth and
containing 540 digital optical sensors and 16 IceTop surface stations with 64
sensors. With the integrated AMANDA-II experiment this is the world's largest
neutrino telescope in operation. The construction status of IceCube is
presented along with an update on physics performance study for the detection
of high energy neutrinos. The potential of the full km^3-scale telescope in the
search for astrophysical sources is also addressed.
