First, go to this page, and click on the link that says,
Forgot Apple ID ?
and follow procedure there.
Then once that process gets you your Apple ID back into your immediate memory, you can proceed to go to that page anew, and enter your Apple ID or email address, and click on Continue, and follow through the process to get your password ***** also.
Then with your Apple ID, and its password, back again, you proceed to Activate your iPhone.
