WhatsApp drops support for BlackBerry and Nokia OSes

WhatsApp has announced that it intends to focus on only 99.5 percent of the addressable mobile market, and will be dropping support for BlackBerry OS as well as BlackBerry 10, Nokia S40, and Nokia Symbian S60.

Along with the changes, the company said in a blog post it will also drop support for Android version 2.1 and 2.2, and Windows Phone 7.1.

"While these mobile devices have been an important part of our story, they don't offer the kind of capabilities we need to expand our app's features in the future," WhatsApp said. The company explained that it intended to boost security features in the messaging service, and when it started out, around 70 percent of smartphones were either BlackBerry or Nokia, with Android, iOS, and Windows Phone now representing 99.5 percent of the market.
