Also tried a Cingular-branded Motorola Razr V3 (http://onlinestorez.cingular.com/cell-phone-service/cell-phones/cell-phones.jsp?v=1&q_deviceId=cdsku9870054&WT.svl=mod15) with very similar results. In the moto's case pairing itself seemed to succeed but the 770 popped up a "service discovery failed" message. I tried to pair several times, always with the same results. This phone has DUN, as I have verified earlier by sdptool-browsing it from my laptop and connecting to the DUN RFCOMM port with minicom (AT commands work). D.
