If you're like me you have your awesome former mobileme, whatever@mac.com or me.com . You like that email address. But..... before there was a mobileme you had also been purchasing apps , music , movies, dark matter from that nasty email address that was tied to your itunes account when you were 17, and using hotmail or comcast as your email.
Of course Apple still refuses to offer any sort of merging of accounts. So you get IOS 5, on setup it asks for your iCloud account, well I didn't really know which account to give it, so I gave it the one that I knew purchases were associated with, hoping I could add additional accounts as well. So I do that, and everything is fine, except I can't change the primary iCloud account!!! I can change random stuff like iMessage from , but a lot of the functionality is directly linked to the primary account.
Solution:
On initial IOS 5 setup, using your iCloud account that you want to use. Then later, go to the Store options, under Settings, and change that account to your account that all of your purchases are associated with.
