The following devices can’t be upgraded to iOS 7: Original iPhone, iPhone 3G, iPhone 3GS, original iPod touch, iPod touch 2nd-gen, iPod touch 3rd-gen, iPod touch 3th-gen, original iPad.
Here’s a full list of which iOS 7 features will be available in each country, since your location as well as your device will affect which features you get.
How to update to iOS 7
There are two ways to update your iPhone, iPad or iPod to iOS 7: over the air (via Wi-Fi) or through iTunes.
Before you upgrade to iOS 7, though, there are a couple of housekeeping jobs to do. First, update your apps as certain out-of-date apps won’t work in iOS 7.
Second, check if you have enough free storage space as the update requires at least 1.4GB of memory for temporarily storing the download during the update. You can check how much space is available by tapping Settings > General > Usage. The list of apps will tell you which ones are using up your phone or tablet’s storage. Typically, it will be the Photos app, which is full of your images and videos.
