The latest version of Apple's Mobile OS (iOS 7) is being pushed out to most Apple users today. Most because it is not available for older generations of Apple products like the iPhone 3GS or the first generation iPad. But if you have any version newer than those, you will be able to update to iOS 7. And this update is a big one!

In fact, it's the biggest iOS change since 2007! The new software has a modern feel, complete with bold colors and typefaces. It is also more efficient, due to a super accessible search bar. Notifications are easier to see (and even easier to dismiss), and one of the coolest new updates is the predictive directions feature, which tell you how long it will take to get to a commonly visited destination. Siri is better too, helping inside third-party apps (if the app developers wrote the code correctly). And tabs in Safari will be stacked instead of side-by-side, which may take some getting used to.
Overall, we think the iOS is a great step forward for Apple. Maybe not quite as big a step as we had hoped, but it's definitely an upgrade. But what if you can't update to iOS 7? Apple has updated the App Store to allow users with older iOS versions to download the last known compatible version of apps, an option not previously available to those with older generations of Apple products.
