I just got an iphone. Can I setup my own Apple ID and share my wifes itunes account?

How do I see the answer to this? Tapping on "see the answer in context" does nothing.

Do you both sync to the same computer or have separate computers? If separate, my recommendation is to set up individual apple IDs and then use home sharing if you want to share music or apps or other content. I don't think you HAVE to though.
