whatever your primary gmail address is, that is the address that your contacts, apps, tasks, calendar entries will be synced to. that is the beauty of google.
so if you have an old android mobile and you are moving to the ONE, after you sign in on the ONE with your old android gmail address you used, that data will be sent to the ONE.

Is there an easy way to move contacts stored on the phone over to google? And JUST use google for contacts?
