    ArcMap 10, Add unique ID field

      How do you add a unique ID field in ArcMap 10?

      in ArcMap 9.x i always made a new ID field and used the field calculator expression "UID + 1" in ArcMap 10 there doesn't appear to be a UID field, seems to have been replaced with "ObjectID" and this won't work to update my field.

      Any ideas? sure there's a better / proper way of doing this.
