This graph is kinda confusing to read, but I'm parsing it correctly then it looks like Blackberry had a pretty massive surge around 2009-2010 - well after the release of the iPhone. That is actually surprising to me.

I suppose that might be due to the market growing - in which case Apple looks like it's relatively flat starting around 2010 but in reality the number of users were increasing along with the market.
