How to re-install facetime and utilities folder?

I got my new iPhone 4 today and used the "restore from back-up" command in iTunes to port everything over.

When I restarted, I don't have facetime, and the utilities folder was gone. I assume that all the utilities had in it was calculator, stocks, weather, etc. And I still have those from my old phone.

1) How do I get facetime back?
2) Anything in utilities that has been added or other apps Apple included that I may have lost on the upgrade/porting process?
