sony ericsson w900i

Today I bought my self a new SE W900I
But the troubles came when i tried to configuring it using bluetooth.
First I chose to configure a new bluetooth unit, by pressing on the bluetooth sign in the upper right corner.
When I have done that, I cross of the "mobile phone" square.
Then i get a code that I am supposed tu punch on my mobile phone, to finish the configuration prosess.
After i punch in the code, the mobile asks me if I want to add the Mac to my units, and I press yes..
After that nothing more happens.
The configuration does not continue, but just gets stuck at that point. The Mac does not freez, I can close the program and try again, but without any more luck.
I have even tried paying and downloading som plug-in from nova media, that is supposed to help me with this, still nothing!
I tried using the USB cable that followed, same thing over again.
When I want to add a phone to Isync, it finds the phone,but it says that isync can not connect to this unit.
So I am all out of ideas.
It worked so fine with mine S700i, and now this..
Is it possible that it is something wrong with the phone? Or has any body else experienced this?
Anybody got any ideas? I sure would appreciate it!
