Blackberry rolls-out BBM for iOS and Android

The long-awaited Blackberry Messenger (BBM) app for iOS and Android was rolled-out on Monday with Blackberry reporting 10 million downloads in the first 24 hours of it going live.
Prior to the launch, Blackberry had described demand as “amazing” with about six million people having signed up for updates at bbm.com.
The app, which was initially planned for September but was delayed following the release of a leaked version, is being rolled-out gradually to deal with the demand, with users waiting in line, having downloaded the app, before gaining full access.
BBM goes head-to-head with cross-platform mobile messaging apps like WhatsApp, which now boasts 350 million active users, a figure that could have been more easily achievable for Blackberry had it released the app two years ago when sales of its devices were higher.
