It's a difficult soldering job as the components are surface mounted and the solder joints of the pins are very small, but if you use a magnifying glass and a very thin tipped soldering iron, you could pull it off. Maybe, just try to re-solder/re-heat the bead of solder that's already on the joint where the pin goes into the board and it will be enough.

I'm a sucker for anything that will save me $400, and I also really liked using the hands free....
