If you are someone who migrated from MobileMe to iCloud and have an existing me.com or mac.com email address then Apple have just announced that you will also receive the equivalent icloud.com email address.
The icloud.com emil address should be functional but the old style mac.com and me.com will still work.
If you so wish, you can reconfigure your email clients to use the new email address or stick with what you have been using. Regardless of which one you choose as your default, you will receive email addressed to all types of addresses.
Its also worth noting not everyone will have all types of email accounts.
- If you had a working mac.com email address as of the 9th July 2009 and migrated to iCloud before 1st August 2012 then you can use all three email addresses, mac.com, me.com and icloud.com
- If you created a new iCloud account before 19th September 2012 or migrated from Mobile Me before 1st August 2012 then you get me.com or icloud.com
- If you created a new iCloud account after 18th September 2012 then you just get icloud.com
