If this is somehow a nice gesture to everyone who suffered through MobileMe, then consider me happy! 🙂
I've been with the service back when it was called iTools and when they gave you 20MB of space. Then upgraded to .Mac, then MobileMe, and now iCloud.
My iPhone didn't show the date, but in System Preferences > iCloud on my Mac it showed up. I hope it sticks, I want the extra space for phone backups and it would be very nice to keep it that way.
