Can I use the on-camera flash along with an off-camera SB-700 on my Nikon D5000?

Question

I recently bought an SB-700 flash for my D5000 and I was wondering what would be my options to use this as an off-camera flash along with the on-camera flash.

Is it possible? TTL cable, wireless transmitter, whatever...

Answer

Yes, using the on-camera-flash in manual power setting and the SB-700 in SU-4 optical slave mode.
