Interesting thing to note, Samsung Mobile's Singapore website now has the New PC Studio 1.3.0 IJ1 as a Software download in the GalaxySpica section, only Samsung Kies was there before. Maybe you guys should check if your region's website has them up. I find it odd that it isn't version 1.4.0 though, since that seems to be the one capable of linking up to the phone properly.
