I think BB is still up in the air. I think corporate America is using the iPhone has the new high-end phone like the Blackberry used to be.
I work for a national corporation and they’ve shifted things. They still use Blackberries, but its for sales reps. Regional Managers and higher all get iPhones now.
I’m still rooting for Windows Phone to dominate the #3 position and maybe in a few years become #2.
