My Blackberry Curve 8310 will not find my brother's Samsung SGH-a437 via bluetooth. And he cannot find me either. We both are enabling our bluetooth and each of us searches for a device and yet nothing comes up. Why is this happening and what can I do to solve it?

Thanks.

options > bluetooth > menu > options > enable bluetooth > make sure you are also discoverable while he is searching.

You know I have that issue with me and my wifes phone I can find everyone elses 8230 or other blackberry phone but I cant find my wife and she has an 8320 . Is there a reason why this is happening?

Yup, I'm discoverable and followed those steps and it won't work.
