Hello,
I am a former BlackBerry employee who has dealt with this issue directly. If you with to get the data from a .bbb file to your android device there are several ways of doing so, .csv may not be the best route to go. The fields are not converted properly and you will run into duplicate contacts and missing fields. The way I would recommend going about this is using a test device that I have at my disposal, and using it to restore the data using the previous BlackBerry ID that is associated with it, and use it to sync the data to your google mail account. From there once the data is confirmed on the google side of things you can use the google mail sync options on android to pull the data back down.
There are obstacles with going about this process, however I am confident this can be done fairly easily, and quickly.
Please follow up with me and we can discuss this further.
Thank You,
Donald
