I just added intrepid-proposed to my apt sources and updated kbluetooth4.
When I run kbluetooth4 I can send a file to my phone using bluetooth when I rightclick the bluetooth icon in the systray and select send file. But when I select Device Manager, click on 'New' and then 'Next', 'Next', my phone is not displayed although in the terminal I do see the bluetooth name of my phone coming by.
Attached is the logfile of a kbluetooth4 session in which I first try to find my phone ('Idioot de 2e') using the device manager and then send a file (info.txt) to my phone.
This all is on Intrepid with KDE 4.1.
