Forget the new and powerful iPhone 5S or the colorful and cheap iPhone 5C: The biggest draw to the iPhone is the upcoming iOS 7, which is jam-packed with features that make the iPhone business-friendly.
The major upgrade was first unveiled at Apple's Worldwide Developer's Conference earlier this spring and has been in the hands of developers ever since. Now iOS 7 is poised to hit the general public in a week, Sept. 18.
If Apple's upgrade track record is any indication, just about everyone with a relatively new device -- iOS 7 works on iPhone 4 and later, iPad 2 and later, iPad mini and fifth-generation iPod touch -- will upgrade to iOS 7 almost immediately.

A recent survey from enterprise mobility company Cortado suggests that a good portion of them have a lot of catching up to do. Cortado surveyed 1,350 IT directors and administrators to access the impact of iOS7 in the enterprise. A whopping 42.5 percent said, "I don't know."
If you're one of those behind the ball, Cortado put together a handy infographic to help you out:
