I also have problems with bluetooth, My computer running win7 64bit can see the legend and vise versa but am unable to get past pairing to connection.
I also have the same problem sending any files to my wifes LG GW620, we can pair the phones but when I try to send pic or audio it fails, looking at the two phones menus the LG gets more options when you long press the device you are sending to, in the bluetooth settings page theres 'unpair' and 'options', if you go the 'options' route theres a connect screen, on the Legend there is no 'options' when you long press the device to connect to, just the 'unpair' tab.
Im wondering if there is a fault in the software rendering bluetooth useless on my Legend, I have recently got this phone and did update it via the phones menu to 2.1, do you think this is where the problem lies, I have read about the problem regarding threaded text massages being the wrong way round and wondered if the update could have messed up the bluetooth as well
