My original iTunes account (Apple ID) was set up with a hotmail.com address back when all I had was an iPod. I've decided to move to a primarily Apple-based ecosystem away from Google and Microsoft as much as possible, and my first step was a new iPhone.
Along with the new iPhone, I also have a shiny new iCloud.com address. Unfortunately, this is an Apple ID in it's own right, so I can't change the email address of the old ID to this icloud address, nor can I merge the two Apple IDs.
Can I set up my iPhone to use the old ID (hotmail.com) just for iTunes and the App store, and the new ID (icloud.com) for everything else (mail, contacts, calendar, notes, photos)?
