Switching my wife's iCloud account name?

[Imola Ghost]

I just installed iOS 5 GM on her iPad 2 and when I signed in I put her Apple ID as her iCloud account name.

Is there a way to change it to he MobileMe account? I've went into the settings and selected the "iCloud" preferences and her Gmail account is in there but it's greyed out.

I have the same problem. Does anyone know the possible reasons why the user name in iCloud preferences would be grayed out?

Interesting note: When I installed iOS 5, it asked what Apple ID to use for iCloud, so I entered one, and it seemed to work.

But when I went to preferences, I see a different one... The one I used to use in iOS 4 I guess.
