can't log in
I can't access my iCloud or iDisk or mobile me on macpro, iPad, iPad mini, iTouch.
MacBook Pro (15-inch Mid 2009), Mac OS X (10.7.5), no access on my iPad mini, iPad 2
MobileMe and iDisk closed over a year ago and were replaced by iCloud so you can no longer access those. Did you go to Settings>iCloud and sign in with your Apple ID to create an iCloud account?
