I changed my user ID for iCloud when I changed my email address. When I go into iCloud it shows my old I'd but under primary email address it shows my new one. When I sign into the App Store and iTunes I use new I'd and old password with no issues. However every time I write a new email or reply to an email a window ops up asking for my iCloud password and it shows my old ID! I can just hit cancel and it goes away and I can write but it's a pain in the behind! Any ideas? Hope this is clear!
