Once you click the Move to iCloud button the process starts. I haven’t tried, but I bet there’s no going back once you’ve done this so think about it first.
MobileMe gets its move on into the iCloud.
That’s it you are all done!
Some next steps…
Congratulations — you are all done!
Now log into http:\\www.icloud.com with your Apple ID or MobileMe ID and have at it.
This is the screen you’ll see after logging in. It looks like iwork.com has finally grown up.
Customize your iCloud badge with your own photo, setup your time zone and language.
Select your time zone.
Add your own image to customize your iCloud experience.
As you can see I like to have a little fun with this image stuff. Shazam! You are all done. Now you can enjoy iCloud.
