iPhone contact info isn't saved when you hit save (once)

The iPhone's interface for adding new contact information should be more robust.
If, for example, you are getting someone's contact information and you enter their name and hit "save" and then get their email and hit "save" it is very easy to think that you are done. Let's say you have an interruption at this point such as a text message or call. This information will be lost and you will get no indication that you are losing it. It would be best if the iPhone started saving the information as soon as you hit save. Somewhat worse would be returning you to where you were in the info entering stage when you reentered the contacts application.
