Well, I'm trying to think this through. Here is what I have: 1. I have a MobileMe account, email@example.com which I will migrate to iCloud 2. I have a iTunes ID account firstname.lastname@example.org I use to buy all apps, songs, books and even everything on the Apple store site. So, when I associate my device which account should link my iPhone, iPad to. If I link to my @me.com then none of my purchases will exist? if I link to my @gmail.com account, than how will my email sync with my phone. From what I read, you can't migrate the 2 accounts into 1. Seems very difficult and Apple should have really thought this through.
