Since the federal government is letting iPhones and Android phone in the network, Blackberry is going to lose a significant market portion.
We've been testing iPhones and Androids for a while now and are about to roll them out soon.
I was a diehard Blackberry user for a long time (personal phone) but after three years of waiting, I moved on to Android. I'm very happy with the move.
I wish Blackberry all the luck in climbing back towards the top tier of smartphones.
