8703e and my original jawbone

Hi all, I just received my 8703e off ebay. So far I have come across a couple of problems. First it keeps losing connection with my Jawbone earpiece, as soon as I make a call and hang-up I lose connection. Also, it needs a password to get on bb messenger, I figure I'm just out of luck about the password. But, any help on these issues would be greatly appreciated. If it makes a difference the Jawbone is one of the original models. I'm gonna buy a Jawbone 2 but want to be sure it will work. Thanks again.
