Berry-a-Code is new free program for BlackBerry devices that translates the area code of unknown numbers to the originating city and state. Currently it supports over 275 US, 24 Canadian and 20 Caribbean area codes. The only requirement is OS 4.x+ on your BlackBerry device. You can check out the software at these links below. Currently I have not found a desktop manager link.
