Blackberry's New Attempt - BBM

The Blackberry Messenger which caught the spark and spread like wild fire is now spreading its arms into other operating system. Whatsapp which can be used on any platform and iMessage for iOS proved to be tough competitors for BBM. Blackberry confirmed that they have 60 million users of BBM at present with 10 billion messages being sent and received everyday. In this quest to get a hold on the exuberance of Whatsapp and iMessage users, Blackberry is now introducing BBM for all the Android and iOS phones.
They are launching an universal BBM app for other phone platforms to increase their number of users. 😁
Will it really affect the craze for Whatsapp/iMessage ?
