No, it's not my business. I'm just a pilot, but I know several places are really depend on Blackberries, and this ruling might affect them somewhat. 'How' remains to be seen.
As for me, I've had a company-issued blackberry at my old job.
At my new employer, I'm just given a mobile phone allowance, and it's up to me which one to use. I chose Blackberry simply due to availability of BBM and ease of email.
However, back home, I'm an iPhone guy, and (un)fortunately, it looks like I'll be an iPhone guy all-around. Doesn't hurt me any...
