Apple's iOS isn't keeping pace with the rest of the smartphone industry, charges BlackBerry CEO Thorsten Heins. The executive makes the claim in a new interview with the Australian Financial Review. "The rate of innovation is so high in our industry that if you donĂt innovate at that speed you can be replaced pretty quickly," he comments. "The user interface on the iPhone, with all due respect for what this invention was all about, is now five years old."
