| | Re: Is BB the most used smartphone in the world
The iPhone is the single most successful smart phone in the world right now. I don't see that changing anytime soon. Android is the most popular OS by sales (not necessarily by installed user base) but that's spread out over many different phones.
BlackBerry still has a large user base but it's not growing as fast as iOS and Android. In places like Africa BlackBerry is still the most popular brand of smart phone.
