> people barely used them for talking to their friends
In the UK Blackberry and BBM remained very popular for a long time.
That Blackberry was additively used for email (even in a business setting) implies a lot of use for friends. The crackberry addicts were emailing their friends, who were likely also work colleagues, fellow execs, etc.
There's a viral quality to emails from BlackBerry devices as well. Didn't they add "Sent from my BlackBerry" to the end of emails by default? And then Apple famously added "Sent from my iPhone" by default to emails from iPhones.
