Apple said that  iOS 6, the next version of its iPhone and iPad operating system,  will be compatible with devices as old as the iPhone 3GS, which is 3 years old. iOS 6 will be compatible with multiple devices but not all features are available on all devices. Macrumors created a nice “infographic” which you can see above, that shows what features are supported on each device.

iPhone 3GS owners will receive iOS 6 features like redesigned App and Music Stores, Cloud Tabs in Safari, Facebook integration, and other improvements — it just won’t include nearly the same number of features as the owners of Apple’s latest and greatest gadgets.
