This is my current setup:
Created new iCloud account through iPhone by selecting Setting> iCloud
Chose to create a new account with an @me.com address, let's call it myappleid@me.com
Then I went to iCloud.com>Mail, and created a new alias. It is my only alias, let's call it myalias@me.com
On the iPhone:
Settings>Facetime, I type in myappleid@me.com, and it's respective password.
The next screen is a screen that displays the above email address, and displays a Next button which I press.
A checkmark is displayed and a new screen appears.
This new screen displays the FaceTime slider showing that it is on. My AppleID is displayed.
Under "You can be reached for video calls at">"Add An Email", I enter myalias@me.com.
As soon as I press the return key, an error pops up:
FaceTime Activation
An error occurred while verifying your email.
The verification process doesn't go through. Not even when I try to 'Resend Validation Email' when I tap the Error'd myalias@me.com email area.
