Apple iOS 8 Is Already Available 

How to Download?

Today Apple releases iOS 8, the latest mobile operating system for your iPhone, iPad, and iPod. The update includes a long list of new features, including interactive notifications that allow you to reply to messages from your home screen, a new intuitive typing technology, self-destructing text and audio messages, and the soon-to-be-available “Continuity,” which allows you to seamlessly switch from activities on your mobile device to your computer.

Additionally, the update will allow you to remove yourself from annoying group text messages, create family accounts to share and regulate iTunes purchases within your family, and monitor your physical activities via the new Health app.
Here’s how to download it:

1. Check to see if it’s compatible with your device.
Apple announced which of its gadgets can handle the update at its Worldwide Developers Conference in June. Check this list to see if your device made the cut: iPhone 4s, iPhone 5, iPhone 5c, iPhone 5s, fifth-generation iPod Touch, iPad 2, iPad 3, iPad 4, iPad Air, and iPad mini.
The tech site Ars Technica has warned that iOS 8 may cause slow performance if you own an iPhone 4s. So, if you own that phone, you might want to stick with the iOS version you have.

The iPhone 6 will ship with iOS 8 installed. So if you’ve already preordered a sparkly new sidekick, you won’t have to worry about this.


2. Back up your gadget.
Your personal stuff/settings will be cleared when updating to a new iOS, so it’s best you save your most recent settings, apps, photos, and emails to iCloud or your hard drive.
If your iCloud account is enabled, just connect to WiFi and plug your device into your computer. iTunes will open, and the name of your device will appear in the upper-right corner like so:

Alternatively, you can back up your device without connecting it to your computer, as long as you have an iCloud account. Just connect to WiFi and tap your Settings app.
Scroll down to iCloud and then tap Storage & Backup. 

Depending on how much crap you’ve accumulated on your phone, this may take a few minutes.

3. Download the update!
There are two different ways to do this. The first is straight from your i-device.
You’ll need a nice, strong WiFi connection and a place to charge your device. Apple usually doesn’t allow you to update without those two things.
Go to your Settings app. Then go to General → Software Update.

This option may take longer, but if you’re away from your computer and need to get iOS 8 as soon as it’s out, it’s the way to go.
The second (faster and better) option is to download the update via iTunes. You’ll need your computer and a charging cable.
(Also, note that the update is a whopping 6GB or so. You might need to delete several photos, videos, songs, and apps to make space.)
Plug your device into your computer and wait for iTunes to open. On the upper right of iTunes’ toolbar, you’ll see the device’s name appear, just like when you backed it up. Click it.
