Chen says BlackBerry phones are the entry point for customers into the company’s security business. BlackBerry can still provide a secure backbone for other devices like iPhones and Android phones, but Chen says you get the most security with a BlackBerry phone. There are a lot of important customers that still need that level of security. “I can only make iPhone so much more secure, but I can’t make it as secure as a BlackBerry device,” Chen said. “If you look at the US Army, they’re still rolling out all BlackBerry. If I tell them there are no more phones, I lose that account. The question is how do you make phones profitable at the volume those people represent?”
