In order to begin using your iPhone, you have to activate it. The activation process is different depending on what model of the iPhone you have and what version of the operating system you're running. If you're using an original iPhone or iPhone 3G, the activation process is based around a combination in-store and iTunes-centric activation. This article does not cover that, since those models are no longer being sold.
This article is for people who haven't had an iPhone before and want to activate their new iPhone. It also assumes that you're using iOS 5 or higher (which is what runs on the iPhone 5 and iPhone 4S, and the 4 and 3GS, if you've upgraded). If you're using an earlier OS or are upgrading from an existing iPhone, use this article.
OK, with that out of the way, let's get started activating your iPhone!
- Buy the Phone - Surprise! The first step in setting up a new iPhone is buying it (though I suspect you already knew that). There are a number of places you can buy an iPhone. Do your research, make a decision, and head to the store or wait for the delivery.
- Ensure iTunes Is Up To Date - This isn't absolutely required if you're running iOS 5 and up, but it's probably a good idea anyway. Learn how to install iTunes. Once you've got iTunes installed or updated, you're ready to proceed
Begin by turning on your iPhone by holding down the sleep/power button in the top right corner. When the screen lights up, you'll see the image above. Swipe the slider to the right to begin iPhone activation.
