Apple Notifying Former MobileMe Members of New iCloud.com Email Address Options
Those new icloud.com addresses have been rolling out gradually over the past several months for former MobileMe members, and Apple now appears to have completed that transition, sending out an email to former MobileMe members notifying them of the new email address option.
All new iCloud Mail accounts now come with an @icloud.com email address. As an existing user, we'd like to offer you this new address as well. We have reserved [MobileMe user name]@icloud.com for you, and you can now use this address with your iOS devices and computers by following these simple instructions.
If you prefer, you can continue to use your current email address just as you always have.
No matter which address you use, you'll continue to receive all your mail, whether it's sent to your @me.com, @mac.com, or @icloud.com address.
