All products probably have (undiscovered) security holes - whether it's issues with the firewall, issues with the management console, SSL vulnerabilities, manufacturer backholes that get discovered later, or vulnerability in the wireless encryption scheme - this is stuff we find out later (if we knew about it earlier, it would have been fixed). Having security updates pushed to your phone is never a bad thing. It's the reason why enterprise Linux distro updates promise security patches (but possibly not bug fixes) for such a long period - because people do care about these things. Security patches are a good thing.
