Hey
I just got the solution for the Bluetooth
So Now you can send any files to your computer through bluetooth..

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
