Try Wine

Wine is a very nice thing, it is a program you can use in order to run applications dedicated for certain platforms on any other one

for example i use it to run some windows application i get to use them on my linux machine, although Wine isn't fully mature yet but a large number of applications run nice on it

Personal Area Network (PAN)

Personal Area Network or shortly (PAN) is a communication network between a group of bluetooth-enabled devices (supporting PAN)

this network can be used between these devices in the same manner as local area connection i.e you can use it to transfer files between two devices or even more you can use it in a twisted way to enable one device to use other device internet connection after configuring a bridge between it and WLAN network

anyway it is a nice technique of communication, i liked it so much and tried to use it but i couldn't because my N80 doesn't support it. i suggest everyone to make use of this powerful facility
