To activate your iPhone you need to ensure that you've inserted your sim card, installed the latest version of iTunes on your computer and then connect your iPhone via the charging/USB cable provided with your iPhone and connect it to a free USB slot on your computer. Your computer will or should recognise the new hardware and iTunes should automatically open. Once this happens you will be prompted via iTunes to register your iPhone. Follow all the steps to register your iPhone. You will then be given the opportunity to copy all music, photos and video's etc onto your iPhone, select from the options what you want to be copied to your phone. It is important to remember that what you copy to your phone will reduce the available memory of your phone, which can limit other things you might want to download and store on your phone such as apps.
