Camera Roll Photo Library and iPhoto special folder-How to make into ONE

-I understand "Camera Roll" category on the iPhone PHOTOS area contains the pics I've taken on my iphone. I know I can move these to iPhoto when I connect iPhone to my computer, then delete off of iPhone.

-Inside iPhoto on my desktop computer I made a folder called: "For iPhone" in which I chose some pics I wanted to be seen on my iPhone; so then inside iTunes under my device's name, under "Sync photos from iPhoto" I have chosen "Selected albums" and only chose the one "For iPhone" (x40 pics) that I made.

-Now when I go to my iPhone after a sync there is:

  1)Camera Roll (x89-as stated I can delete these ok)

  2)Photo Library (x40)

  3)For iPhone (x40)

It seems to me that the "Photo Library" and "for iPhone" have exactly the same photos in them. Is there a way to only have ONE showing with the 40 photos? ie: How to delete or remove that "photo library"?

I know when I take more pics with my iPhone it will auto make a "Camera Roll", and maybe that title will be there always even if I "delete off of iPhone" after importing into iTunes, so understand I may have two categories inside iPhone's PHOTOS area, but don't want THREE.

Thanks ahead for any help re this!
