With the new update to 10.8.2, one of the features enabled was support for @icloud.com email addresses. I took a screenshot to highlight this, view it here. Now, I personally am not sure how the transition to the new standard is going to work out, and I've been chatting with several people who are in the same boat. Currently, if you log in to the icloud.com portal and try to create a new alias off your main iCloud account (which will most likely be a @me.com one), you should only get the ability to make that alias carry the @icloud.com domain, which tells me that from now on every new user who signs up for iCloud will be able to register an email account that will end in @icloud.com with no other option. This is good, and it's the way Apple has done these changes. However, I am having issues finishing the process of setting up any new alias, and here's another screenshot for that. For the last day, this has been the case and the problem has repeated itself constantly. Supposedly, everyone with a @me.com address would be able to get the equivalent ending in @icloud.com with the move to 10.8.2 and iOS 6, respectively, but maybe right now it's too early and that's why a lot of peopleincluding myselfare seeing this little problem. What do you think? Are any of you here having the same issue? I may point out as well, that the issue in question seems to happen only when a user with a @me.com address attempts to create an alias that will carry the new @icloud.com domain. To confirm this, I went ahead and created an Apple ID ending in @icloud.com and I did not encounter any issues whatsoever; the account is now up and running.
