Nokia 6180 via bluetooth

Hi there. I can connect my Nokia 6280 via bluetooth using standart kdebluetooth. I can transfer all files and everything. But then after following instruction to setup /dev/mobile and link it to /dev/rfcomm0 and when I open kmobiletools I just get error "An Error occured when initialising phone device. Please check your configuration and try again". I don;t understand what is going wrong because I get no error coming up when I set up rfcomm0. unless I am doing it wrong. Help

Thank you

Alex
