Back then you had to download Seesmic from the company's Web site. Now you can get it directly from BlackBerry App World online or from the App World app on your smartphone.
Although Seesmic's interface is a bit light on features--like support for multiple accounts--it has added some enhancements that better integrate its Twitter app with the BlackBerry ethos. Chief among these are compliance with the BlackBerry's spell checker and auto-corrector, which will both help keep you from misspelling tweets or forgetting to capitalize an "i." The app has also become sensitive to keyboard shortcuts. In addition to the usual BlackBerry shortcuts T and B, to take you to the top and bottom of the page, are R to reply, D to send a direct message and F to retweet. Here is the full list of mapped shortcuts.
You can now vary your font size among small, medium, and large fonts. Seesmic for BlackBerry also lets you mark a tweet as a favorite in your timeline, but doesn't yet have a dedicated Favorites screen. In addition, Seesmic is now available for phones running 4.5 of the BlackBerry's operating system.The previous build, version 1.0.6 beta, only worked on BlackBerrys 4.6 and up.
