BlackBerry launched Blackberry Messenger (BBM) for Android and iOS platforms. BlackBerry claimed last week that 6 million Android and iPhone customers had pre-registered for the launch.

This launch of BBM for Android and iOS platforms was slated for September 21 and September 22 respectively but owing to a leaked apk BBM file on Android, the company had to call off the launch.

A blog post on BlackBerry’s official blog by Executive Vice President, BBM, Andrew Bocking, said, “The demand for BBM on Android and BBM on iPhone continues to be amazing. About six million people signed up for information about BBM at BBM.com. As you know, in just seven hours, about one million Android users were using the unreleased version of BBM for Android. What you don’t know is that more than one million people have found creative ways to “side load” BBM on their iPhone. This is incredible.”

BBM is being launched in a phased manner. The blog post further said, “To help manage this unprecedented pent up demand for BBM, we are implementing a simple line-up system to ensure a smooth roll out. If you are among the millions that took the time to sign up at BBM.com, you can start using BBM immediately without waiting in line. If you didn’t sign up in advance, don’t worry – we are focused on moving millions of customers through the line as fast as possible.”
