How to Download and Install iOS 8 on Your iPhone, iPad, or iPod Touch

The annual iOS update cycle rolls on. This time, Apple is launching the eighth iteration of its operating system for the iPhone, iPad and iPod touch. iOS 8 will be available as a free download on Wednesday, September 17. The download and update process itself is quite easy, but there are a few important things you should keep in mind before you download iOS 8. Here's a guide to help you through the process with zero fuss.

Backup

The next step is possibly the most important in the process - backup. Apple generally has had a great track record with no major cases of data loss reported after updates, but it is always better to be safe than sorry. We've previously covered the entire process of taking a backup of your iPhone and the steps are very much the same for other Apple devices. Here's how to create a backup of your Apple device.

1. While you can take a backup of your device on iCloud, we recommend that you use iTunes as the entire process is more reliable, especially if you have spotty connectivity.
2. Plug in your Apple device to a PC or Mac. Open iTunes and click iPhone (or iPad or iPod Touch) on the top-right, next to iTunes.
3. Under Manually Back Up and Restore, click Back Up Now to start backing up your Apple device. This process takes some time especially if it's the first time you are backing up data. Make sure you have time to spare before you do this. It took us a little over 40 minutes to take a backup the first time, though your mileage may vary depending upon the storage capacity of your iPhone and how much data you have stored.
4. Once essential data from the default apps has been backed up, iTunes will ask you if you want to transfer purchases. This basically takes a backup of all the apps installed on your phone, along with data downloaded within those apps. To do this, you will have to sign in with your Apple ID.

If you don't have access to a computer, then you can use iCloud Backup. Remember that only 5GB is free and you'll have to pay Rs. 60 per month for 20GB of storage on iCloud. But since the actual apps themselves are not backed up to iCloud - only app data is, along with your photos, videos and other information - free storage is usually enough for most.

1. To start backing up, on your iOS device, go to Settings > iCloud > Storage & Backup.
2. Turn on the switch marked iCloud Backup. You'll get a warning telling you that your iPhone will not back up to your computer automatically. Tap okay.
3. Once iCloud Backup is on, tap Back Up Now. This will start backing up your data to iCloud.

Wait for the backup to finish before proceeding further. You should see the Last Backup time (which should appear right below Back Up Now) correspond to something recent once the backup is completed.

Download and install iOS 8

Now that your data is safe, let's see how to download and install the iOS 8 update. You can update your device either directly via Wi-Fi or by connecting it to a PC or Mac and downloading the update via iTunes. Downloading it directly is easier, so let's try that first.

1. On your iOS device, make sure you're connected to Wi-Fi (you can't download updates over cellular data) and plug it in to a power source.
2. Go to Settings > General > Software Update
3. On this screen, you'll see a message telling you your software is up to date. When iOS 8 is released, the message will tell you that a newer version is available. Tap Download and Install.
4. Now the device will begin downloading the update. Once the download is complete, you'll see a pop-up asking if you'd like to install the update. Tap Install. That's it. When the update is installed, your iPhone will restart.

In case you want to install the update via iTunes, follow these steps.

1. Download and install iTunes.
2. In case you already have iTunes, update it to the latest version. You can do this by going to the menu bar in iTunes and clicking Help > Check for updates on a PC or iTunes > Check for updates from the menu bar on a Mac.
3. Once you have got the latest version, connect the iOS device to your computer. In iTunes, select your device from the bar on the top-right.
4. Now click on the Summary tab and click on Check for Update.
5. To download and install iOS 8, click Download and Update.

Once the install is completed, follow the on-screen instructions to setup your iOS 8 device. You may be promoted to set up your device as new, restore from an iCloud Backup or restore from an iTunes Backup after reboot - select option 2 or 3 based on the backup method you selected above. You may also be prompted to re-enter your Wi-Fi or Apple ID/ iCloud password, or enable location services, while iPhone 5s users may be prompted to enter their fingerprint again - all that is normal.

That's all. Now you're ready to enjoy iOS 8.
