Apple's iOS 5 went live to users of the company's iPads and iPhones on October 12. It's also the operating system behind Apple's latest iPhone 4S, which also hits the streets on Oct. 14. Consumers will flock to the operating system as they look forward to getting their hands on the latest and greatest features available on Apple's lines of devices. CIOs, though, are left pondering whether iOS 5 brings any new value to the enterprise. The good news is: It does. The operating system is well-built, comes with a host of improvements, and should deliver all the functionality that a company might need, sans support for BlackBerry Enterprise Server, which is available only for Research in Motion's line of products. With iOS 5, we get Siri voice recognition software, iMessage, the new Notification Center and the platform's consistent security -- among the other features that make Apple's iOS 5 an enterprise winner.
