Nokia N70 mobile doesn't connect via Bluetooth - Help?

Hi,

some days ago I switched from a MB to a MBP. During installation of the new MBP I've recovered all information from the old MB from a Timemachine backup.

Everything worked fine - except the Bluetooth connection between MBP and my mobile, a Nokia N70.
iSync didn't synchronize any longer - "device not found".
To solve the problem I deleted the N70 from the bluetooth settings and tried install it again. During the installation the wizard asked me to enter a code into my mobile. After entering the code into my mobile the installation wizard went on with the installation - "gathering more informationen about Your mobile" (originally in German, I don't know the exact wording in English). The installation wizard won't go beyond this step of the installation - it is never finished. So I am also not able to use iSync via Bluetooth of course.

Using iSync connecting with a USB cable works fine, all the data from my mobile is synced with my MBP.

Has anybody any clues how to solve the problem? I tried to get any clues from the console but I don't know the Mac OS X environment good enough...

thx in advance
