How to download

1. Does your device support iOS 7?
iOS 7 is supported by iPhone 4, iPhone 4S and iPhone 5; iPad 2, third and fourth-generation iPads, iPad mini; and the fifth-generation iPod touch. Also, certain features of iOS may not be available on all devices. For instance, the iPhone 4S doesn't support features like AirDrop and live filters in the camera app. The iPad 3 also doesn't support AirDrop.

2. Backing up your device
If you don't regularly backup the data on your iPhone or iPad, now is a good time. You'd like your favourite apps and settings to transition to iOS 7 and for that you'll need to take a backup.

You can take a backup your device in two ways, backing up to iCloud (Apple's servers) or by backing up data to your Mac or PC via iTunes.
3. You can either install iOS 7 directly to your iOS device through an over-the-air Software Update via Wi-Fi or connect it to your computer and install the update through iTunes.

To upgrade over the air, go to the Settings app, tap on General and then on Software Update. Wait for the update message to appear and tap on Download and Install.

If you want to install the update through your PC or Mac instead, connect your device to the computer and wait for iTunes to open or fire it up manually. You'd typically get a software update prompt but if you don't just go to the device Summary page by clicking on the name of your iOS device, and click on the 'Check for Update' button, and click on Download and Update.
4. After updating your iPhone to iOS 7, you'll see a welcome screen, post that you'll be prompted to enable Location Services, following which you will get a page where you can select whether you want to set up your iPhone as a new phone, restore from an iCloud Backup or restore from an iTunes Backup. You'll need to enter your iCloud credentials and stay connected to a Wi-Fi network if you select the iCloud backup option or ail need to connect your phone to your computer if you select the iTunes option. After a few more prompts asking for your iCloud and iTunes credentials and pages displaying terms of use, you'll finally see your Home screen with a brand new OS.
