RIM has launched v4.1 of its Facebook app for BlackBerry OS 5 to 7.1 smartphones. Significant upgrades include easier access to News Feed filtering options, a refreshed profile design, the ability to set your profile photo, photo tags and some bug fixes.

“Facebook 4.1 makes it even easier to access your News Feed Filters. You can now select Show All, Status Updates, Photos or Links directly from the Navigation List as well as from your BlackBerry Menu Key,” BlackBerry says. “Facebook 4.1 has an exciting new look and feel for your Profile page. You’ll be able to view your cover photo, larger profile pictures plus there’s a new ‘more actions’ button that allows you to view another user’s cover photo in full screen mode.”

“With Facebook 4.1 you can easily change your profile photo using the BlackBerry Menu Key on your smartphone. Simply select a photo from an album, press the BlackBerry Menu Key and select ‘Set As Profile Picture’,” the company adds. “Facebook now allows you to view multiple photo tags in your News Feed. You can see the profile names for up to two people tagged with your photo. For three or more people tagged with your photo, the number of people tagged will be displayed. You can then click on this to find out who’s been tagged.”

As far as bug fixes, notification clearing and duplicate friend request issues have been addressed.

The app should be available in BlackBerry World within the next 24 hours.

Facebook just released a big update to its Android SDK so developers can do more with Facebook on Android apps. More on that here.
