If you have change your blackberry device from PIN A to PIN B, here are the steps to recover your chat history:
1. Open your memory card on a computer search for this folder:
x:\Blackberry\im\Blackberry Messenger\A
2. Now rename A folder into B, so its become
x:\Blackberry\im\Blackberry Messenger\B
3. Now you can put back your memory card into your new device with your previous BBM chat history restored

NB: If you open your chat history you will see your OLD PIN with your friend PIN, If you want to see your NEW PIN, it will take more time to do it :)

You can also do these steps in your new device directly through FILE MANAGER application.

You can also do the same thing for your other chat application like Yahoo, MSN, etc.
