It all depends on whether or not BlackBerry users will remain loyal now that the brand's unique selling point is gone.
One of the most exciting announcements this at at BlackBerry Live was that the company’s beloved messaging app, BlackBerry Messenger, would finally be coming to both Android and iOS platforms this summer. As with any software undertaking of this size, it is sure to have been in the works for some time, and in the case of Android we figure it has been in the works since at least late 2011.
This means that the blackberry fever will reduce in Nigeria, and it also means that even with techno android you can use BBM chat to ping other blackberry users.
Several ladies have lost their virginity and self worth because of blackberry.

I've seen series of videos where some ladies were ripped naked because they stole a blackberry phone. One of the ladies even committed suicide because she can't bear the shame any longer. If these ladies would had known that a time is coming when they will be able to ping with their Techno and Nokia phones, they would have be patient.

Many people have abuse the purpose of smartphones, this phones are meant for business, but many Nigerians only use it for pictures and to prove to their friends that they are using the latest phones.
