I have found a modded firmware for Wave II since the old method was not working so this is the working firmware for Wave II users.

IT is Bada 1.2 (S8530XXJK2) with (S8530CISJK3)
IN THIS FIRMWARE SPOOFING WORKS 
  
This firmware is for Europe but anyone can use it even if he is living in any part of the world.
