It's here!!! Head to mobile.blackberry.com on your Berry's browser to download!
* Note to existing Leaked Facebook 1.5 Users: If you previously were running a leaked copy of Facebook 1.5 on your device it sounds like you may need to do a handheld wipe to rid your BlackBerry of the leaked version's database. The official version doesn't seem to recognize the in-between leaked version, so it creates a new duplicate database. Deleting the leaked version and doing a battery pull before installing the official doesn't quite seem to do the trick. However, you can still install and run the new version even if you don't do the wipe... you're just hogging a bit of resources to no benefit. If you were running a leaked version, you can drop your findings on this in the comments. *
