I just bought a Jabra Bluetooth ear piece a couple of days ago and now I want to get a new phone so I am looking for what the ear piece said it had to have in order to have to be compatible with it.It also said A2DP and I was looking at a Samsung Behold and this IS on the specs on the phone and it looks like it is for music.But what does the other stuff mean ? I looked under bluetooth and didn't see anything on there that was similar to it on the phone.And ALSO...what is Android ??? Is it like a version of a smart phone or what ? Thanks so much for any help.
