I am having the same issue. Set up on a macbook pro, iMac, and phone, and get this error on my iMac at home. Still need to do my iPad. Also disabled my mobile me mail - said account was expired. Mobile Me in sys prefs says everythings been moved but won't let me log in to iCloud. Just woke up hoping the servers would have cleared out but same issue. I use a different Apple ID for itunes but it doesn't work with that either. Hope someone has an answer for this as the home iMac is my primary storage for my other devices. Haven't even tried wifi sync yet because of all these errors!

Since this is a first generation MacBook Air, and I primarily use my iPad these days, along with my iMac for heavier duty stuff, I decided to determine whether the issue was hardware or software related. So, I erased the MacBook Air and reinstalled a clean copy of Lion. After the reinstall, I was able to login to iCloud in System Preferences just fine.
This means, there's some errant file in the System that's preventing the login to proceed.

So if I were to wipe my mac and reinstall Lion you think it my solve my problem of not being able to login into iCloud with my Apple ID? I had thought of doing that.

just wait a few hours then you will be able to.

I waited 12 hours for this issue to go away, and so proceeded with erase/install solution. Carlo may be right and the issue will be resolved on the server end. Only time will tell, but I wanted to put my Air back into use, and it is, tonight.

Just delete /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist via Terminal:
sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
Works fine for me!

Thanks for the potential solution! Hopefully, someone else here will now try this out before spending a whole day reinstalling Lion, apps, and data, as I did!

This was a No-Go for me. Any other ideas folks? I am running 10.7.2 Lion Server, on a Mac Pro 3,1. Additionally, the App Store is still showing 10.7.2 as an available update, though when I click it I get a message that tells me to go to Software Update. I have gone back and Re-Installed the 10.7.2 Combo Update for Server, and still have both problems. Would not like to start over as am running Server.
