Oh man, iCloud is having issues. Out of the blue, my Apple ID (@me.com) stopped taking my password in iTunes and on the app store on my iPhone/iPad. I tried to log into appleid.apple.com to manage my account, and upon entering my ID and PW, I got "Fatal internal error occurred". I started a support chat with MobileMe support and they said try again in 5 hours. Then I started Googling the issue and it seems like people have been having similar problems for 5 WEEKS. Most anecdotes indicate Apple has no idea what the problem is or how to fix it. Anyone figured out a solution?
