Even though BlackBerry doesn’t have as much applications and games as iPhone, blackberry was able to keep competing with iphone thanks to its messaging service. Although this service is expensive , blackberry was able to retain a big number of subscribers.
However BlackBerry is expected to lose its subscribers because of the new iPhone iOS, iOS 5,which have a new messaging application similar to bbm called ” iMessage ” , iMessage allows iPhone holders to send unlimited free text,photo,audio and video messages. iMessage is a built in application , that works over wifi or regular mobile data plan.
The effects of ” iMessage” on BlackBerry are going to be heavy , the prices of BlackBerry devices will fall as Blackberry users give up the “expensive service” and move to the free alternative iMessage.
