phone using Bluetooth? Can it work without a bluetooth adapter?

If you have a laptop then you probably have bluetooth built in your computer, otherwise you have to buy a bluetooth dongle

Make sure the dongle you buy has USB 2.0 interface!

if you want to use bluetooth, you must have bluetooth device conected to your computer and bluetooth turned on your phone, search bluetooth devices from computer and if it finds your phone, go ahead transfer music. bluetooth adapter is nessecery. :/
