Each and every iDevise user is concerned about iOS 6 accessibility when it arrives for the end users. If you’re among those wondering whether the  iOS 6 features will make it into your iOS device, Apple has published on its iOS 6 preview page that transmits which features are restricted to which device. Check out the list below provided below:

• Siri is still exclusive for the iPhone 4S and the 3rd-gen iPad.
• Find My Friends and Find My iPhone are not available in all areas.
• Flyover and turn-by-turn navigation is only available for the iPhone 4S, iPad 2 and the new iPad. Cellular data charges may be applicable.
• FaceTime over a cellular network is only available for iPhone 4S or 3rd-gen iPad with GSM capabilities.
• Shared Photo Streams is available on iPhone 4 or later, iPad 2 or later and Mac with OS X Mountain Lion.
• Offline Reading List will be available for iPhone 4 or later and iPad 2 or later.

VIP list and VIP and Flagged smart mailboxes will be available for iPhone 4 or later and iPad 2 or later. So as we can probably assume, Apple has taken care not only for the flagship device owners, but for those still holding old ones too, including even the iPhone 3GS. However, iPhone 3GS owners will be missing a lot of the key features that makes iOS 6 a genuine update.
