Write a letter to your Apple ID first
My phone iphone4s forgot Apple ID, now cannot activate the serial number is C3*******TC0, can you help me activate or detect the Apple ID?
And then receive the solution as follows
First, Apple has a special unlock team, you need to be like them to show the purchase vouchers, invoices, boxes and store information after taking photos to send to their mailbox, they will help you unlock the device! Contact Tel: 400-627-2272
Activate lock team mailbox: purchase_validation_apac@apple.com
Second, if the formalities are not complete, we download and install the Safari browser, because it seems that the Apple ID only in the Safari browser can be very smooth use, everyone find the Apple ID login page, and then we can start our next move.
Third, we click on "Forget Apple ID" and proceed to the next step. Then we need to enter the relevant information we provide when we register, and we'll just fill it in. After entering our last name and first name, and after registering the mailbox, click Next, then we come to the prompt to select the authentication information. Here we choose to "Use e-mail".
Four, in fact, here, we found our Apple ID, because our Apple ID is actually our mailbox number, if we received an email from a certain mailbox, then this email address is our Apple ID. Well, it seems we have successfully found our Apple ID.
