Yea amish , just write a script to start dund and all other commands to initialise it.Also if you see in KDEbluetooth configuration, you can run commands on detection of a device..so you can have your script automatically run once the PC detects your fone!And after that just starting any internet-accesing app on fone will directly initiate a connection through BT as its set default by GNuBox!! You can do lot more automated stuff using KDEbluetooth, just see help of KDEBluetooth (KDEBluetooth Handbook its called i think) there are examples there.
