Seesmic, which develops mobile and desktop clients for social media platforms including Twitter, will wind down support for its BlackBerry smartphone client later this month.

Seesmic for RIM's BlackBerry

Seesmic will no longer be available for BlackBerry after June 30.

"Effective June 30th, Seesmic will discontinue support for BlackBerry in order to focus development efforts on our most popular mobile platforms: Android, iOS and Windows Phone 7," the startup said in a brief statement posted Monday to its blog. Seesmic goes on to recommend that users impacted by the move consider trying out one of its other smartphone apps or its desktop and web alternatives.

Seesmic did not expand on the thought process behind its decision to walk away from BlackBerry, although contrasting the Research In Mobile (NASDAQ:RIMM) operating system against its "most popular mobile platforms" speaks volumes. Long the frontrunner in the U.S. smartphone market, BlackBerry is now the third largest operating system in the category: comScore reports that as of April 2011, BlackBerry represents 25.7 percent of the American smartphone segment, behind Google's (NASDAQ:GOOG) Android at 36.4 percent and Apple's (NASDAQ:AAPL) iOS at 26 percent.

A recent IDC forecast anticipates BlackBerry will fall even further behind its rivals in the years ahead. IDC projects Android will control more than 40 percent of the global smartphone market by the end of 2011 and reach 43.8 percent market share by 2015; Microsoft's (NASDAQ:MSFT) Windows Phone, which is replacing Symbian as Nokia's (NYSE:NOK) primary smartphone OS, will command just 3.8 percent of the market as 2011 closes but will rise to 20.3 percent by 2015. Apple's iOS will represent 18.2 percent of the worldwide smartphone market as 2011 ends, and IDC projects it will make up 16.9 percent by 2015. Although BlackBerry is expected to account for 14.2 percent of the market in 2011, IDC looks for it to slide 13.4 percent four years from now.

Business Insider reports that other BlackBerry developers have privately indicated plans to follow in Seesmic's footsteps and abandon their BlackBerry efforts as well.
