Another couple phones: The moto v360 pairs on the 1st try. The MPX220 smartphone can be paired to the device if you become root and open bluetooth, but have no option for DUN. (File transfer only) The moto v600 did not work at first, but after repeatedly hitting OK, it bonded. I am waiting for the new samsung t809 and the moto PEBL in the mail and will update as soon as i see if they bond and DUN works. (on a side note, it also did bond with the verizon "V" but that's all i did.)
