Hey
I just read some thread about the bluetooth in leopard.
Becuase when you want to send a file to your computer through (phone) bluetooth it show " can't be send "
here is the solution:
1- On each Mac OS X 10.5-based Mac, from the Apple menu, choose System Preferences.
2- From the View menu, choose Sharing.
3- Check (click) the "On" box next to Bluetooth Sharing.
4- Close the Sharing preferences window.

I try it and its works Fine
Now you can send whatever you want through bluetooth to your computer
