iPad 2 error

[tomster]

A notification saying I don't have enough iCloud storage won't go away if I press close. It won't let me turn off the device or go into apps. I can't turn on more settings to waste more battery. Please help. Thx

There's a thread discussing the same problem: http://www.ipadforums.net/ipad-3-forum/102080-frozen-screen-icloud-notification.html
Perhaps it helps.
