The way it works behind the scenes is that your Mobile operator contacts Apple and submits your phone imei number with a request that it be white listed (Added to the unlocked register held by Apple)
You will receive an e-mail or SMS text from your Mobile operator (Not Apple) inviting you to connect your iphone via the USB cable to iTunes where you follow the instruction on screen.
Normally takes anything from 3 days to as much as two weeks to receive this e-mail/SMS from your Mobile operator.
On completion you will get a congratulations your iPhone is now unlocked message.
