Feeling left out of the Twitter fun as a user of a Blackberry device? Are you a bit jealous of your iPhone and Android using friends who get to have fun using the official Twitter app for their respective devices? If so, your day has finally come because the folks at Twitter have released the “official” app for Blackberry too.

Late last night, Twitter for BlackBerry smartphones started to roll out into a full launch. The application reportedly features many user requested bug fixes, tweaks and feature additions received from users during the app’s long Beta period.

Here’s what you can expect from this app:

“Go to User” – the ability to access any user’s profile from anywhere in the application using auto-complete functionality for followers.
Push Notifications for Direct Messages
Timeline Support
Following and Followers
Posting, Sending, Deleting , Replying and Retweeting Tweets
User/Saved/Keyword/Proximity Search
Tweet Photos/Links
Trending Topics
Seamless integration into core BlackBerry applications
URL Shortening
Auto-Update

If you’re a Twitter user like we are at The Flickcast, you’ve probably come to know and love the ability to reply or forward your friend’s Tweets, known as “@ tagging” or “retweeting”. It’s a great way to spread important news, argue on the internet, or just comment on the silly things your friends are saying via Twitter. But if you’re not a Twitter user, but want to do the same thing with your Facebook status, you’re in luck. Why?

Facebook has just launched this feature as well.

It works very similar to @ tagging, but instead of using Twitter usernames you’ll use your Facebook friend’s names after the “@”. This makes it easier to reply to your friends, since you won’t have to memorize any complicated usernames.

If you tag someone, they’ll recieve a notificaition, and vice versa. You can also reference groups that you belong to on Facebook or events you plan on attending. The gap between Twitter and Facebook is narrowing and blurring.

Will you use this new Facebook feature, or continue to retweet your friends on Twitter?
