Although I have both a Blackberry and an iPhone, I find that my iPhone gets more mileage as my personal handset, while my Blackberry is used primarily for business. And it seems that a majority of people feel the same way: a recent study shows that out of 600 smartphone users, 73 percent carried an iPhone as their personal phone, while 59 percent of Blackberry, HTC, and Nokia owners used theirs for business.

So now I'm interested: do you use your smartphone primarily as your business or personal phone?
