Hi James,
Sorry for correcting you, but I thought I'd clarify a few of your
comments, so that confusion doesn't arise...

The jacks only have 4 pins (and not six).
None of the modules (some 40 or so different types) I have are
doubled sided PCBs - they all only have copper tracks on one side.
However, you are right in that it would often be tricky to do what
you want to because often the jacks *are* mounted on the solder side,
and so would required their removal to cut the track underneath.
