i do not have bluetooth built in on my ibook (i thought at the time i would never use it), but now i would like it for wireless apps such as a mouse- maybe the mighty mouse when its bluetooth! and my cell phone. and my main use would be my cell phone (nokia 3660), any advise on a certain usb dongle (and whats with that name? dongle?) i know certain ones have different ranges, and there also different classes of them. anything would help. thanks guys/ladies!
