I just bought a new Nokia N73 M. Now, I need to buy a bluetooth dongle but do not know much about them. What should we look for in a dongle before buying one? Today I brought one from the shop of my regular computer vendor. He asked 250 rupees for it but the connection with it was very unstable so I returned it. I don't have much money left. Just 500 more. So please suggest a good dongle that does not cost much but the connection is good and stable.
