I’ve been a big fan of Seesmic Desktop for quite some time now and have been wondering when and if they planned on releasing a Seesmic application for BlackBerry smartphones. @BRSDiddy just brought it to my attention that they have just released one!

Features:

• All your timelines
  Seesmic for BlackBerry groups all your Twitter timelines into one simple application. Whether you want to scroll through your friends timeline, check on a saved search, view a list or want to find a private conversation with a friend, everything is one click away from the main menu.
• Saved search and list support
  Searches and lists saved on your Twitter account are automatically imported and made available inside the BlackBerry application – a first for a Twitter application the BlackBerry.
• URL Shortening
  We integrated the same URL shortening capability than in our popular Desktop client. Just type a URL, press the shortening button and we’ll transform your long URL into a really small one so you have more space for your tweets.
• Background Notifications
  While it is running in the background, Seesmic for BlackBerry will alert you to received Direct Messages and @Replies that require your attention. This is done using the familiar system-wide icon notification bar that alerts you to new mail, sms messages and voicemails.

According to the Seesmic download page there are two versions available. A beta v1.0 for BlackBerry devices running OS 4.6 and higher, and an alpha v1.0b for the Tour 9630 and Storm 9500/9530/9520/9550. Right now there is no support for devices running OS 4.5 and lower.

To download Seesmic head to seesmic.com from your BlackBerry Browser or check out the product page here for more info. Since these applications are beta and alpha I would recommend first making a backup before installing them.  Also keep in mind that since these are beta and alpha versions they might not be perfect just yet so if you have feedback or need help email Seesmic at support@seesmic.com.

I’ve included some of the demonstration videos after the jump. Let me know how you like the Seesmic Twitter app in the comments!
