It seems that I can log into my icloud on my mbp or my iphone using <username>@apple.com, <username>@mac.com, <username>@me.com, or <username>@icoud.com and I end up at the same account. Are all the accounts I listed above separate accounts that are synchronizing as soon as I log in? The problem I am having is I have purchased apps on my iphone that are not showing up in my Purchased Apps list. I am being told they were purchased by a different Apple ID and as far as I know I only have the one. If the above are all different accounts is there any way to combine them? Pretty confused on this issue. Any help would be really appreciated.
