Use the white chord that came with your Iphone. Plug the small end into the UBS port of your computer and the large end into the Iphone. Your computer will recognize the Iphone and should pull up your Itunes account. If it doesn't, just click on your Itunes account and open it. On the left hand margin of the screen about halfway down you will see your Iphone listed. Click on it. On the summary page at the right bottom of the screen you have an option to sync your phone. Click on it to sync the information from the Iphone to your Itunes.
