i have the motorola w430 which is basicallly the same a the Razr
i have not had any problems disconnecting
if the other person hangs up it automatically disconnects and goes back to the radio or i can disconnect by pushing the U-connect button
not sure how to D/Lthe phones contact list, i'm not a big phone person so i just added my contacts manually one day when i was messing with the MyGig
you may want to try paring your phone again as maybe something didnt pair correctly
