If you see BlackBerry announcing a million or so new users in the next few days, its not because the companys finally seeing an increase in sales. Its because Alicia Keys ex-employer has kept its promise to launch BBM for Android 2.3 on Google Play after weeks of beta testing. The previous Android version of the cross-platform messenger only worked on devices running Ice Cream Sandwich (Android 4.0) or higher, but existing users can now reach more of their friends.
