Once the final version of IOS 6 in the autumn of this year is published, all icloud users will have the opportunity to create
their own e-mail account with the Endung@iCloud.com. This insight comes from the release notes of iOS 6 Beta 3, which was released Monday evening:
" icloud.com email addresses are now available for icloud mail users.
As is evident from the Releaes notes, all me.com addresses are automatically converted into icloud-mail addresses. The old-me.com addresses are expected to remain there still. Anything else would be totally annoying for all users. Apple commented on this but not yet.
Users of signing up for new Apple ID, or enabling their mail on icloud account for the first time, will automatically receive icloud email address instead of a me.com email address. icloud users with me.com addresses that have been used with iOS 6 beta 3 will receive on icloud email address that matches their me.com address.
