I went to facebook.com and did a search, and you can download it from there as well and those of you not on a blackberry plan and have just a regular data plan, it works with this also. You also will not need to get the notifications because you don't have a BB data plan but it will connect to your data connection.
You can get it now from
http://www.blackberry.com/facebook/mobiledownload
Just incase if it doesnt let you download you will might get the following errors:
- You will get a blackberry page saying something about active X.
- Or you will get a HTTP Error 500 message.
If that the case then look at the top of your screen saying allow Active X or something to that effect? If so allow it to run. If your BlackBerry isn't connected to your computer you should be prompted to connect your Blackberry, once you do that it will load the application. Have fun.
