Apple has announced that iOS 8 will be available for download on 17 September, and that means you're probably wondering if your device will work with all the new software features.

Well stop wondering. Pocket-lint has detailed below exactly which devices support which features. It's not a complete list just yet, but we plan to update regularly, so keep checking back. Keep in mind as well that iOS 8 includes several smaller changes, which we assume will work with most handsets, though Apple has yet to specify either way.

Let us know in the comments if we missed anything or if you're curious about support for a feature.

Not everyone is eligible to install iOS 8 on their iPhone or iPad. More specifically, Apple usually limits mobile operating system updates to newer devices. The company has already named which devices are compatible with iOS 8 (listed below), so see if your device can update before getting all excited.

The following devices are compatible with iOS 8: iPhone 4S, iPhone 5, iPhone 5C, iPhone 5S, fifth-generation iPod touch, iPad 2, iPad 3, iPad 4, iPad Air, iPad Mini, and iPad Mini. The iPhone 6 will presumably ship with iOS 8 installed.

We've listed some of the new features in iOS 8, below, alongside which existing Apple devices support the features. We will update this list regularly as Apple reveals more specific information about which devices support which features.

Apple has an all-new Photos app that includes new search functions and smart albums. It appears as though any device that can install iOS 8 will support the new Photos app and its new features.
