Arduino Funnel(Fio) soldering jumpers for Xbee

Hi, I was wondering which jumpers I should solder for the xbee radio to work properly with the Fio. I've seen some tutorials where they solder the terminal above the on-off switch, but I wonder if this is for a very specific esoteric example. For a regular xbee radio to work with the Fio. Which jumpers should I solder together, and where are those jumpers on the fio?

Thank you so much:) :smiley:
