BBM to invade iPhone and Android

After years of keeping its once-very-popular messaging system confined to just its phones, this Saturday, Sept. 21 BlackBerry will finally release its BlackBerry Messenger or BBM for the iPhone and Android. The news comes on the heels of reports that the struggling phone maker will lay off up to 40 percent of its employees before the end of the year.

For the most part, the app will work just as it does on current BlackBerry phones. It will allow users to send messages to their friends or groups of friends without using up text messages. The messaging platform, however, once very popular with BlackBerry users, now has steep competition from other popular chat apps that are out for multiple mobile platforms, including Kik and WhatsApp.
