Comment 1 for bug 237284

Same thing happens to me too. The only thing I can do is to browse the files from my phone, and copy the file to the desktop.

Other problems:
 * Sending file from ubuntu to phone gives out obex unsupported errors, but the file will get sent, eventually.
 * Sending file from phone to ubuntu is as reported in this bug. Phones used, N70, N95 and N73, all reports "Sending Failed"
 * Double clicking on a file when in Browse Device mode gives Obex unsupported error, but dragging the file out to the desktop works.

I've not tried:
 * Using the phone as modem
 * Using ubuntu as a bluetooth network server,
 * or serial port access.
