I already have a 6+ which I've been using for both work and personal. I've now been given a 6 to use at work, with a new number. What would be the best way to set it up? I need to get my work email and contacts over to the new phone, but none of my other email accounts, photos, music etc. I can't seem to figure out how to do that. And should I set up a separate iTunes account and Apple user ID?
