In trying to work out how to sync my iPad and iPhone 4, I've deleted my iCloud info, emails,pics, the lot. I can log in to iCloud from iPad but when I click on Mail, it comes up with a list of email providers. When I click iCloud, it again asks me to log in. When I do so, it tells me this account is already taken!!
Not very good with techy stuff. Thought I'd nothing better to do than sync the iPad and iPhone and taaa-daaa, it would all go smoothly. NOT.
