In order to being using your iPhone, you have to activate it using iTunes. This is a step-by-step guide to everything you need to know about iPhone activation to get you started using it right away!
NOTE: This how-to applies only to the first-generation iPhone. The iPhone 3G uses a different activation process. The iPhone 3GS uses basically the same process as the 3G.

Once that’s done, unpack the iPhone, set it on the included dock, and connect the dock to the computer. This will prompt iTunes to show you the first installation screen. Click continue to begin.
