I am a new Motorola Droid 3 user. I have tried 3 different blueteeth....a Jabra BT135, a Plantronics 520 and a Samsung HM3500. All three have the same issues. 1.) the connection between the earpiece and the phone breaks frequently. Sometimes when this happens, the phone automatically goes to speakerphone, sometimes not. 2.) it does not recognize many of the contact names and the names that it gives as options aren't even close. 3.) Frequently it will say "Opening message" when I request it to make a call. The issues defeat the purpose of hands free, since I usually have to pull off of the road and manually use the contact list to make a simple phone call or to reconnect the bluetooth.
