I'm asking, but I'm doing some looking and searching as well, just getting conflicting info. I've got a gmail address for the App Store purchases. I've got an iCloud address I use for email/calendar/photostream/documents/etc. if like to use one address for everything. Is there any reason I need an iCloud email address? Or would a gmail address do everything if that's my Apple ID? If I can use the gmail, what's my best way to sync my current calendar/photostream/documents/reminder/etc to the gmail address I already use for App Store/iTunes purchases. I understand I can't merge, so how would I transfer the info? Can I just logout of my ipad, login with the gmail address and it will sync the info from my ipad to the gmail iTunes account? I'm trying to be certain I don't lose anything I need.
