Facebooks seems unstoppable these days. Aside from securing an exclusive advertising partnership with Microsoft, it’s also making some waves in the mobile arena with the release of its software application for the Blackberry Smartphones.

You can download this free mobile app at www.blackberry.com/facebook/mobiledownload. Depending on your wireless provider, wireless data charges may apply.

T-Mobile USA is the lucky one to be the first carrier to carry this new application. It enables the mobile users to connect with Facebook faster and easier. Key features include:

1. Receive notifications and messages automatically through BlackBerry platform’s push-based architecture
2. User can also set a unique alert (vibration and/or ringtone) for Facebook related content
3. Quickly access essential features to let users quickly change their status, upload a photo, add a friend, poke someone, write on a Wall, or send a message.
4. Invite friends to join Facebook and accept new friend requests
5. Quickly snap and post pictures along with a caption and tags
6. View the Status of friends
7. Read, compose and reply to messages even while offline

It’s too early to capture the general sentiments of Facebook fanatics. However, an early adopter is disappointed with this new app, claiming it is utterly useless because it can’t receive messages from other people.

In a press release, Research in Motion President and Co-CEO Mike Lazaridis stated:

Facebook is one of the fastest growing web destinations among BlackBerry smartphone users and it has become an important element in the evolving fabric of personal communications. Facebook and RIM share a vision for enhanced mobile communications and social networking based on open, standards-based platforms and this has allowed us to produce a rich mobile application for Facebook users that leverages the push-based architecture, multimedia features and industry-leading usability of the BlackBerry solution
