-If you established a rescue email address, there will be a link on the "Passwords & Security" page of id.apple.com.  Clicking the link will send the reset to your rescue email address (NOTE:  This is not the same address as your Apple ID email)

-If there is no link on the page, then you didn't establish a rescue email address.  Contact AppleCare at 800.694.7466 (If you are in the US), and ask for account security.  You will need to answer some questions to verify your identity, AND you will need access to a computer to generate a temporary support pin.

-If you are not in the US, click http://support.apple.com/kb/HT5699 - Apple ID: Contacting Apple for help with Apple ID account security
